Just a side note to clarify:
Both char* and wchar_t* are most likely unicode stings. The difference 
is that char* is encoded in UTF-8 (at leased 1 byte per character) and 
is backwards compatible with standard ASCII, and a wchar_t* is encoded 
in UTF-16 (at leased 2 bytes per character) and is not compatible with 
ASCII.
To convert between the two, you need some sort of UTF library like 
http://sourceforge.net/projects/utfcpp
