L'<c>' where <c> is a literal character or escape sequence will be converted
by mbtowc into the character set used for wchar_t for your compiler
*this is compiler vendor specific*. (For Windows programmers using
Microsoft's compilers (or compilers compatible with it) L'<c>' would
indeed turn into the Unicode equivalent of <c>.)
fopen ALWAYS expects arguments of type char *, not wchar_t *.
Some compiler vendors (following Microsoft) have created an extension
_ftopen which -does- take wchar_t * arguments. For these environments
the use of L"wb" (notice the ", NOT ' ) with _ftopen does indeed give the
intended result.
Please make sure you consult chapter 5 in Unicode 2.0 as well as your
compiler vendor's runtime library reference. If you don't have a copy of
Unicode 2.0 see http://www/unicode.org.
