-    @class wxStringBuffer
-
-    This tiny class allows you to conveniently access the wxString internal buffer
-    as a writable pointer without any risk of forgetting to restore the string
-    to the usable state later.
-
-    For example, assuming you have a low-level OS function called
-    @c "GetMeaningOfLifeAsString(char *)" returning the value in the provided
-    buffer (which must be writable, of course) you might call it like this:
-
-    @code
-        wxString theAnswer;
-        GetMeaningOfLifeAsString(wxStringBuffer(theAnswer, 1024));
-        if ( theAnswer != "42" )
-            wxLogError("Something is very wrong!");
-    @endcode
-
-    Note that the exact usage of this depends on whether or not wxUSE_STL is
-    enabled. If wxUSE_STL is enabled, wxStringBuffer creates a separate empty
-    character buffer, and if wxUSE_STL is disabled, it uses GetWriteBuf() from
-    wxString, keeping the same buffer wxString uses intact. In other words,
-    relying on wxStringBuffer containing the old wxString data is not a good
-    idea if you want to build your program both with and without wxUSE_STL.

     wxString is a class representing a Unicode character string.
     version wxWidgets 3.0.
 
     wxString is a class representing a Unicode character string.

-    wxString uses @c std::string internally to store its content
-    unless this is not supported by the compiler or disabled
-    specifically when building wxWidgets and it therefore inherits
-    many features from @c std::string. Most implementations of
-    @c std::string are thread-safe and don't use reference counting.
-    By default, wxString uses @c std::string internally even if
-    wxUSE_STL is not defined.
-
-    wxString now internally uses UTF-16 under Windows and UTF-8 under
-    Unix, Linux and OS X to store its content. Note that when iterating
-    over a UTF-16 string under Windows, the user code has to take care
-    of surrogate pair handling whereas Windows itself has built-in
-    support pairs in UTF-16, such as for drawing strings on screen.
-
-    Much work has been done to make existing code using ANSI string literals
-    work as before. If you nonetheless need to have a wxString that uses wchar_t
-    on Unix and Linux, too, you can specify this on the command line with the
-    @c configure @c --disable-utf8 switch or you can consider using wxUString
-    or std::wstring instead.
-
-    Accessing a UTF-8 string by index can be very inefficient because
-    a single character is represented by a variable number of bytes so that
-    the entire string has to be parsed in order to find the character.
-    Since iterating over a string by index is a common programming technique and
-    was also possible and encouraged by wxString using the access operator[]()
-    wxString implements caching of the last used index so that iterating over
-    a string is a linear operation even in UTF-8 mode.
-
-    It is nonetheless recommended to use iterators (instead of index based
-    access) like this:
-
-    @code
-    wxString s = "hello";
-    wxString::const_iterator i;
-    for (i = s.begin(); i != s.end(); ++i)
-    {
-        wxUniChar uni_ch = *i;
-        // do something with it
-    }
-    @endcode
-
-    Please see the @ref overview_string and the @ref overview_unicode for more
-    information about it.
-
-    wxString uses the current locale encoding to convert any C string
-    literal to Unicode. The same is done for converting to and from
-    @c std::string and for the return value of c_str().
-    For this conversion, the @a wxConvLibc class instance is used.
-    See wxCSConv and wxMBConv.
-
-    wxString implements most of the methods of the @c std::string class.
-    These standard functions are only listed here, but they are not
-    fully documented in this manual. Please see the STL documentation.
+    wxString uses @c std::basic_string internally (even if @c wxUSE_STL is not defined)

     The behaviour of all these functions is identical to the behaviour
     described there.
 
     You may notice that wxString sometimes has several functions which do

-    the same thing like Length(), Len() and length() which
-    all return the string length. In all cases of such duplication the
-    @c std::string compatible method should be used.
-
-
-    @section string_construct Constructors and assignment operators
-
-    A string may be constructed either from a C string, (some number of copies of)
-    a single character or a wide (Unicode) string. For all constructors (except the
-    default which creates an empty string) there is also a corresponding assignment
-    operator.
-
-    @li wxString()
-    @li operator=()
-    @li ~wxString()
-    @li assign()
-
-
-    @section string_len String length
-
-    These functions return the string length and check whether the string
-    is empty or they empty it.
-
-    @li length()
-    @li size()
-    @li Len()
-    @li IsEmpty()
-    @li operator!()
-    @li Empty()
-    @li Clear()
-
-
-    @section string_access Character access
-
-    Many functions below take a character index in the string. As with C
-    strings and arrays, the indices start from 0, so the first character of a
-    string is string[0]. An attempt to access a character beyond the end of the
-    string (which may even be 0 if the string is empty) will provoke an assert
-    failure in @ref overview_debugging "debug builds", but no checks are
-    done in release builds.
-
-    This section also contains both implicit and explicit conversions to C style
-    strings. Although implicit conversion is quite convenient, you are advised
-    to use wc_str() for the sake of clarity.
-
-    @li GetChar()
-    @li GetWritableChar()
-    @li SetChar()
-    @li Last()
-    @li operator[]()
-    @li wc_str()
-    @li utf8_str()
-    @li c_str()
-    @li wx_str()
-    @li mb_str()
-    @li fn_str()
-
-
-    @section string_concat Concatenation
-
-    Anything may be concatenated (appended to) with a string. However, you can't
-    append something to a C string (including literal constants), so to do this it
-    should be converted to a wxString first.
-
-    @li insert()
-    @li append()
-    @li operator<<()
-    @li operator+=()
-    @li operator+()
-    @li Append()
-    @li Prepend()
-
-
-    @section string_comp Comparison
-
-    The default comparison function Cmp() is case-sensitive and so is the default
-    version of IsSameAs(). For case insensitive comparisons you should use CmpNoCase()
-    or give a second parameter to IsSameAs(). This last function is maybe more
-    convenient if only equality of the strings matters because it returns a boolean
-    @true value if the strings are the same and not 0 (which is usually @false
-    in C) as Cmp() does.
-
-    Matches() is a poor man's regular expression matcher: it only understands
-    '*' and '?' metacharacters in the sense of DOS command line interpreter.
-
-    StartsWith() is helpful when parsing a line of text which should start
-    with some predefined prefix and is more efficient than doing direct string
-    comparison as you would also have to precalculate the length of the prefix.
-
-    @li compare()
-    @li Cmp()
-    @li CmpNoCase()
-    @li IsSameAs()
-    @li Matches()
-    @li StartsWith()
-    @li EndsWith()
-
-
-    @section string_substring Substring extraction
-
-    These functions allow you to extract a substring from the string. The
-    original string is not modified and the function returns the extracted
-    substring.
-
-    @li substr()
-    @li Mid()
-    @li operator()()
-    @li Left()
-    @li Right()
-    @li BeforeFirst()
-    @li BeforeLast()
-    @li AfterFirst()
-    @li AfterLast()
-    @li StartsWith()
-    @li EndsWith()
-
-
-    @section string_case Case conversion
-
-    The MakeXXX() variants modify the string in place, while the other functions
-    return a new string which contains the original text converted to the upper or
-    lower case and leave the original string unchanged.
-
-    @li MakeUpper()
-    @li Upper()
-    @li MakeLower()
-    @li Lower()
-    @li MakeCapitalized()
-    @li Capitalize()
-
-
-    @section string_search Searching and replacing
-
-    These functions replace the standard @e strchr() and @e strstr()
-    functions.
-
-    @li find()
-    @li rfind()
-    @li replace()
-    @li Find()
-    @li Replace()
-
-
-    @section string_conv Conversion to numbers
-
-    The string provides functions for conversion to signed and unsigned integer and
-    floating point numbers. All functions take a pointer to the variable to
-    put the numeric value in and return @true if the @b entire string could be
-    converted to a number.
-
-    @li ToLong()
-    @li ToLongLong()
-    @li ToULong()
-    @li ToULongLong()
-    @li ToDouble()
-
-
-    @section string_fmt Writing values into the string
-
-    Both formatted versions (Printf/() and stream-like insertion operators
-    exist (for basic types only). Additionally, the Format() function allows
-    you to simply append a formatted value to a string:
-
-    @li Format()
-    @li FormatV()
-    @li Printf()
-    @li PrintfV()
-    @li operator>>()
-
-
-    @section string_mem Memory management
-
-    The following are "advanced" functions and they will be needed rarely.
-    Alloc() and Shrink() are only interesting for optimization purposes.
-    wxStringBuffer and wxStringBufferLength classes may be very useful
-    when working with some external API which requires the caller to provide
-    a writable buffer.
-
-    @li reserve()
-    @li resize()
-    @li Alloc()
-    @li Shrink()
-    @li wxStringBuffer
-    @li wxStringBufferLength
-
-
-    @section string_misc Miscellaneous
-
-    Miscellaneous other string functions.
-
-    @li Trim()
-    @li Truncate()
-    @li Pad()
-
-
-    @section string_compat wxWidgets 1.xx compatibility functions
-
-    The following functions are deprecated.
-    Please consider using @c std::string compatible variants.
-
-    Contains(), First(), Freq(), IsAscii(), IsNull(), IsNumber(), IsWord(),
-    Last(), Length(), LowerCase(), Remove(), Strip(), SubString(), UpperCase()
+    the same thing like Length(), Len() and length() which all return the
+    string length. In all cases of such duplication the @c std::string
+    compatible methods should be used.
+
+    For informations about the internal encoding used by wxString and
+    for important warnings and advices for using it, please read
+    the @ref overview_string.
+
+    Since wxWidgets 3.0 wxString always stores Unicode strings, so you should
+    be sure to read also @ref overview_unicode.
+
+
+    @section string_index Index of the member groups
+
+    Links for quick access to the various categories of wxString functions:
+    - @ref_member_group{ctor, Constructors and assignment operators}
+    - @ref_member_group{length, Length functions}

+
+    This tiny class allows you to conveniently access the wxString internal buffer
+    as a writable pointer without any risk of forgetting to restore the string
+    to the usable state later.
+
+    For example, assuming you have a low-level OS function called
+    @c "GetMeaningOfLifeAsString(char *)" returning the value in the provided
+    buffer (which must be writable, of course) you might call it like this:
+
+    @code
+        wxString theAnswer;
+        GetMeaningOfLifeAsString(wxStringBuffer(theAnswer, 1024));
+        if ( theAnswer != "42" )
+            wxLogError("Something is very wrong!");
+    @endcode
+
+    Note that the exact usage of this depends on whether or not @c wxUSE_STL is
+    enabled. If @c wxUSE_STL is enabled, wxStringBuffer creates a separate empty
+    character buffer, and if @c wxUSE_STL is disabled, it uses GetWriteBuf() from
+    wxString, keeping the same buffer wxString uses intact. In other words,
+    relying on wxStringBuffer containing the old wxString data is not a good
+    idea if you want to build your program both with and without @c wxUSE_STL.
