-    @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.
-    wxString uses @c std::string internally to store its content
-    unless this is not supported by the compiler or disabled
-    specifically when building wxWidgets. Therefore wxString
-    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.
-
-    Since wxWidgets 3.0 wxString internally uses UCS-2 (basically 2-byte per
-    character wchar_t and nearly the same as UTF-16) under Windows and 
-    UTF-8 under Unix, Linux and OS X to store its content. 
-    Much work has been done to make existing code using ANSI string literals
-    work as before. If you 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.
-    
-    Since iterating over a wxString by index can become inefficient in UTF-8
-    mode and iterators should be used instead of index based access:
-
-    @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 "wxString overview" and the
-    @ref overview_unicode "Unicode overview" for more information
-    about it.
+    The wxString class has been completely rewritten for wxWidgets 3.0
+    and this change was actually the main reason for the calling that
+    version wxWidgets 3.0.

 
 

-    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 is a class representing a Unicode character string.
+    wxString uses @c std::basic_string internally (even if @c wxUSE_STL is not defined)
+    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::basic_string. (Note that most implementations of
+    @c std::basic_string are thread-safe and don't use reference counting.)
+
+    These @c std::basic_string standard functions are only listed here, but
+    they are not fully documented in this manual; see the STL documentation
+    (http://www.cppreference.com/wiki/string/start) for more info.

     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 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.
-
-    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 operator<<()
-        @li operator+=()
-        @li operator+()
-        @li Append()
-        @li Prepend()
-
-        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()
-
-        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()
-
-        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 build", 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()
-
-        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 may be 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 Cmp()
-        @li CmpNoCase()
-        @li IsSameAs()
-        @li Matches()
-        @li StartsWith()
-        @li EndsWith()
-
-        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()
-
-        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 Alloc()
-        @li Shrink()
-        @li wxStringBuffer
-        @li wxStringBufferLength
-
-        Miscellaneous other string functions.
-
-        @li Trim()
-        @li Truncate()
-        @li Pad()
-
-        These functions return the string length and check whether the string
-        is empty or they empty it.
-
-        @li Len()
-        @li IsEmpty()
-        @li operator!()
-        @li Empty()
-        @li Clear()
-
-        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 Mid()
-        @li operator()()
-        @li Left()
-        @li Right()
-        @li BeforeFirst()
-        @li BeforeLast()
-        @li AfterFirst()
-        @li AfterLast()
-        @li StartsWith()
-        @li EndsWith()
-
-        These functions replace the standard @e strchr() and @e strstr()
-        functions.
-
-        @li Find()
-        @li Replace()
-
-        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>>()
+    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.

+    be sure to read also @ref overview_unicode.
