\section{\class{wxString}}\label{wxstring}
wxString is a class representing a character string. Please see the
-\helpref{wxString overview}{wxstringoverview} for more information about it. As explained
-there, wxString implements about 90\% of methods of the std::string class (iterators
-are not supported, nor all methods which use them).
-These standard functions are not documented in this manual so please see the STL documentation.

+As explained there, wxString implements most of the methods of the std::string
+class.
+These standard functions are not documented in this manual, please see the
+\urlref{STL documentation}{http://www.cppreference.com/cppstl.html}).
The behaviour of all these functions is identical to the behaviour described
-there (except that wxString is sensitive to null character).
+there.
You may notice that wxString sometimes has many functions which do the same
thing like, for example, \helpref{Length()}{wxstringlength},
used as it will ensure smoother transition to {\tt std::string} when wxWidgets
starts using it instead of wxString.
-Also please note that in this manual \texttt{char} is sometimes used instead of
-\texttt{wxChar} because it hasn't been fully updated yet. Please substitute as
-necessary and refer to the sources in case of a doubt.

\membersection{wxString::ToAscii}\label{wxstringtoascii}
\constfunc{const char*}{ToAscii}{\void}
-Converts the string to an ASCII, 7-bit string (ANSI builds only).
-
\constfunc{const wxCharBuffer}{ToAscii}{\void}
Converts the string to an ASCII, 7-bit string in the form of
-a wxCharBuffer (Unicode builds only).
+a wxCharBuffer (Unicode builds only) or a C string (ANSI builds).
Note that this conversion only works if the string contains only ASCII
characters. The \helpref{mb\_str}{wxstringmbstr} method provides more

-Attempts to convert the string to a floating point number. Returns true on

\constfunc{bool}{ToLong}{\param{long}{ *val}, \param{int }{base = $10$}}
Attempts to convert the string to a signed integer in base {\it base}. Returns
-{\tt true} on success in which case the number is stored in the location

The value of {\it base} must be comprised between $2$ and $36$, inclusive, or
\constfunc{bool}{ToULong}{\param{unsigned long}{ *val}, \param{int }{base = $10$}}
Attempts to convert the string to an unsigned integer in base {\it base}.

+Returns \true on success in which case the number is stored in the
+location pointed to by {\it val} or \false if the string does not
represent a valid number in the given base. Please notice that this function
behaves in the same way as the standard \texttt{strtoul()} and so it simply
converts negative numbers to unsigned representation instead of rejecting them
Please see \helpref{ToLongLong}{wxstringtolonglong} for additional remarks.

+\constfunc{const char*}{ToUTF8}{\void}

\func{wxString\&}{Trim}{\param{bool}{ fromRight = true}}
embedded {\tt NUL}s (it is also slightly more efficient as {\tt strlen()}
doesn't have to be called).

+\helpref{wxStringBuffer}{wxstringbuffer} or
+\helpref{wxStringBufferLength}{wxstringbufferlength} instead.

\membersection{wxString::Upper}\label{wxstringupper}
The same as MakeUpper.
+This is a wxWidgets 1.xx compatibility function; you should not use it in new code.

+\constfunc{const char*}{utf8\_str}{\void}

+\constfunc{const wxCharBuffer}{utf8\_str}{\void}

+Converts the strings contents to UTF-8 and returns it either as a temporary
+wxCharBuffer object or as a pointer to the internal string contents in
+UTF-8 build.

+Returns an object with string data that is implicitly convertible to

+not be lost (depending on the build) and so this function is only usable for
+passing strings to legacy libraries that don't have const-correct API. Use

-Empty string is false, so !string will only return true if the string is empty.
