Summary: wxString::To8BitData segfaults for apostrophe character

Initial Comment:
If I have a Unicode string containing the punctuation apostrophe (U+2019) and try to convert it to ANSI the whole program segfaults.

I'm using Unicode builds of wxGTK and wxMSW and both have the problem.

Your forgot to include three crucial pieces of information:

(1) wx version
(2) backtrace showing where exactly the crash occurred
(3) a patch against one of the wx samples or a small program that can be
used to reproduce the bug

Changes are high that it's a bug in the code _using_ To8BitData().

> try to convert it to ANSI

Note that this method is *not* appropriate for converting to ANSI,
mb_str() is. To8BitData() is intended *only* for retrieval of strings
previously set using From8BitData() in cases when you need to store
non-string binary data in wxString, it's not meant for anything else.
