Objects:
The following constructors allow you to construct wxString from a wide string
in ANSI build or from a C string in Unicode build.
-\func{}{wxString}{\param{const wchar\_t*}{ psz}, \param{wxMBConv\&}{ conv}, \param{size\_t}{ nLength = wxSTRING\_MAXLEN}}
+\func{}{wxString}{\param{const wchar\_t*}{ psz}, \param{const wxMBConv\&}{ conv}, \param{size\_t}{ nLength = wxSTRING\_MAXLEN}}
Initializes the string from first \arg{nLength} characters of wide string.
The default value of {\tt wxSTRING\_MAXLEN} means take all the string.
\helpref{WC2MB}{wxmbconvwc2mb} method is called to
convert \arg{psz} to wide string. It is ignored in Unicode build.
-\func{}{wxString}{\param{const char*}{ psz}, \param{wxMBConv\&}{ conv = wxConvLibc}, \param{size\_t}{ nLength = wxSTRING\_MAXLEN}}
+\func{}{wxString}{\param{const char*}{ psz}, \param{const wxMBConv\&}{ conv = wxConvLibc}, \param{size\_t}{ nLength = wxSTRING\_MAXLEN}}
Initializes the string from first \arg{nLength} characters of C string.
The default value of {\tt wxSTRING\_MAXLEN} means take all the string.
\membersection{wxString::char\_str}\label{wxstringcharstr}
-\constfunc{wxWritableCharBuffer}{char\_str}{\param{wxMBConv\&}{ conv = wxConvLibc}}
+\constfunc{wxWritableCharBuffer}{char\_str}{\param{const wxMBConv\&}{ conv = wxConvLibc}}
Returns an object with string data that is implicitly convertible to
{\tt char*} pointer. Note that any change to the returned buffer is lost and so
\func{static wxString }{FromAscii}{\param{const char*}{ s}}
-\func{static wxString }{FromAscii}{\param{const char}{ c}}
+\func{static wxString }{FromAscii}{\param{const unsigned char*}{ s}}
+
+\func{static wxString }{FromAscii}{\param{const char*}{ s}, \param{size\_t}{ len}}
+
+\func{static wxString }{FromAscii}{\param{const unsigned char*}{ s}, \param{size\_t}{ len}}
+
+\func{static wxString }{FromAscii}{\param{char}{ c}}
Converts the string or character from an ASCII, 7-bit form
to the native wxString representation. Most useful when using
need to convert from another charset.
+\membersection{wxString::FromUTF8}\label{wxstringfromutf8}
+
+\func{static wxString }{FromUTF8}{\param{const char*}{ s}}
+
+\func{static wxString }{FromUTF8}{\param{const char*}{ s}, \param{size\_t}{ len}}
+
+Converts C string encoded in UTF-8 to wxString.
+
+Note that this method assumes that \arg{s} is a valid UTF-8 sequence and
+doesn't do any validation in release builds, it's validity is only checked in
+debug builds.
+
+
\membersection{wxString::GetChar}\label{wxstringgetchar}
\constfunc{wxChar}{GetChar}{\param{size\_t}{ n}}
\membersection{wxString::mb\_str}\label{wxstringmbstr}
-\constfunc{const char*}{mb\_str}{\param{wxMBConv\&}{ conv = wxConvLibc}}
+\constfunc{const char*}{mb\_str}{\param{const wxMBConv\&}{ conv = wxConvLibc}}
-\constfunc{const wxCharBuffer}{mb\_str}{\param{wxMBConv\&}{ conv = wxConvLibc}}
+\constfunc{const wxCharBuffer}{mb\_str}{\param{const wxMBConv\&}{ conv = wxConvLibc}}
Returns multibyte (C string) representation of the string.
In Unicode build, converts using \arg{conv}'s \helpref{cWC2MB}{wxmbconvcwc2mb}
\membersection{wxString::StartsWith}\label{wxstringstartswith}
-\constfunc{bool}{StartsWith}{\param{const wxChar }{*prefix}, \param{wxString }{*rest = NULL}}
+\constfunc{bool}{StartsWith}{\param{const wxString\& }{prefix}, \param{wxString }{*rest = NULL}}
This function can be used to test if the string starts with the specified
{\it prefix}. If it does, the function will return \true and put the rest
\membersection{wxString::EndsWith}\label{wxstringendswith}
-\constfunc{bool}{EndsWith}{\param{const wxChar }{*suffix}, \param{wxString }{*rest = NULL}}
+\constfunc{bool}{EndsWith}{\param{const wxString\& }{suffix}, \param{wxString }{*rest = NULL}}
This function can be used to test if the string ends with the specified
{\it suffix}. If it does, the function will return \true and put the
\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
\constfunc{bool}{ToDouble}{\param{double}{ *val}}
Attempts to convert the string to a floating point number. Returns \true on
-success (the number is stored in the location pointed to by {\it val}) or \false
-if the string does not represent such number.
+success (the number is stored in the location pointed to by \arg{val}) or \false
+if the string does not represent such number (the value of \arg{val} is not
+modified in this case).

Attempts to convert the string to a signed integer in base {\it base}. Returns
\true on success in which case the number is stored in the location

-valid number in the given base.

+valid number in the given base (the value of \arg{val} is not modified
+in this case).
The value of {\it base} must be comprised between $2$ and $36$, inclusive, or
be a special value $0$ which means that the usual rules of {\tt C} numbers are
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

+location pointed to by \arg{val} or \false if the string does not
+represent a valid number in the given base (the value of \arg{val} is not
+modified in this case). 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
(e.g. $-1$ is returned as \texttt{ULONG\_MAX}).
Please see \helpref{ToLongLong}{wxstringtolonglong} for additional remarks.
+\membersection{wxString::ToUTF8}\label{wxstringtoutf8}
+
+\constfunc{const char*}{ToUTF8}{\void}
+
+\constfunc{const wxCharBuffer}{ToUF8}{\void}
+
+Same as \helpref{utf8\_str}{wxstringutf8str}.
+
+
\membersection{wxString::Trim}\label{wxstringtrim}
\func{wxString\&}{Trim}{\param{bool}{ fromRight = true}}
This is a wxWidgets 1.xx compatibility function; you should not use it in new code.
+\membersection{wxString::utf8\_str}\label{wxstringutf8str}
+
+\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.

\membersection{wxString::wc\_str}\label{wxstringwcstr}
-\constfunc{const wchar\_t*}{wc\_str}{\param{wxMBConv\&}{ conv}}

+\constfunc{const wxWCharBuffer}{wc\_str}{\param{const wxMBConv\&}{ conv}}
Returns wide character representation of the string.
In ANSI build, converts using \arg{conv}'s \helpref{cMB2WC}{wxmbconvcmb2wc}
\constfunc{wxWritableWCharBuffer}{wchar\_str}{\void}
Returns an object with string data that is implicitly convertible to
-{\tt char*} pointer. Note that any change to the returned buffer is lost and so
-this function is only usable for passing strings to legacy libraries that
-don't have const-correct API. Use \helpref{wxStringBuffer}{wxstringbuffer} if
-you want to modify the string.
