129//
130// We need both char* and wchar_t* versions of functions like wxStrlen() for
131// compatibility with both ANSI and Unicode builds.
132//
133// This makes passing wxString or c_str()/mb_str()/wc_str() result to them
134// ambiguous, so we need to provide overrides for that as well (in cases where
135// it makes sense).
136//
137// We can do this without problems for some functions (wxStrlen()), but in some
138// cases, we can't stay compatible with both ANSI and Unicode builds, e.g. for
139// wxStrcpy(const wxString&), which can only return either char* or wchar_t*.
140// In these cases, we preserve ANSI build compatibility by returning char*.
