be wxFONTENCODING\_UNICODE, but only if wxUSE\_ENCODING is set to 1.

{\it output\_enc} encoding.
You must call this method before calling Convert. You may call
it more than once in order to switch to another conversion.
{\it Method} affects behaviour of Convert() in case input character
cannot be converted because it does not exist in output encoding:

Return equivalents for given font that are used

\item wxPLATFORM\_UNIX
\item wxPLATFORM\_WINDOWS
\item wxPLATFORM\_OS2
wxPLATFORM\_CURRENT means the plaform this binary was compiled for.
Examples:

Equivalence is defined in terms of convertibility:

-that you loose special chars like quotation marks or em-dashes
-but you shouldn't loose any diacritics and language-specific
