characters from languages other than English.

+Starting with release 2.1 wxWidgets has support for compiling in Unicode mode
on the platforms which support it. Unicode is a standard for character
encoding which addresses the shortcomings of the previous, 8 bit standards, by
using at least 16 (and possibly 32) bits for encoding each character. This
need for the system to convert all strings the program uses to/from Unicode
each time a system call is made.

many cases it is unwise to write a program which can only work in Unicode
environment. A better solution is to write programs in such way that they may
be compiled either in ANSI (traditional) mode or in the Unicode one.
-This can be achieved quite simply by using the means provided by wxWindows.

Basically, there are only a few things to watch out for:

strings but it is more likely that Unicode strings are wanted in the Unicode

and {\tt \_\_TTIME\_\_} which behave exactly as the standard ones except that
they produce ANSI strings in ANSI build and Unicode ones in the Unicode build.

\item Always use {\tt wxChar} instead of {\tt char}

unless they're already converted to the right representation (another standard

need for {\tt wxT()} in this case) or you intend to pass the constant directly
to an external function which doesn't accept wide-character strings.

Although everything works fine inside the program, things can get nasty when
it tries to communicate with the outside world which, sadly, often expects

You should define {\tt wxUSE\_UNICODE} to $1$ to compile your program in
Unicode mode. Note that it currently only works in Win32 and GTK 2.0 and
that some parts of

compile your program in ANSI mode you can still define {\tt wxUSE\_WCHAR\_T}
to get some limited support for {\tt wchar\_t} type.
