If you use wx functions you don't need to convert it at all.

For example, you can use wxDynamicLibrary and not care about conversions.

The strcpy() is unnecessary, you can just do "dlopen(strPath.ToAscii())"
directly. Of course, this only works if the path has only ASCII characters.

The mb_str() method by default returns the representation of wide string
in the current locale. Whether the function you call expects this or
something else (like a string always encoded in UTF-8 independently of
locale) is another question.
