If you want to base your application on Unicode and run it on Windows
95, you need to translate string parameters to local character sets
before calling API functions. (The only wide character APIs that handle
Unicode on Windows 95 are TextOutW, ExtTextOutW, GetCharWidthW,
GetTextExtentW, and GetTextExtentPointW.)
The API for translating strings from Unicode into the system's default
local character set is WideCharToMultiByte. When you receive
string-based information from Windows 95, you need to translate it into
Unicode by calling MultiByteToWideChar before working with it.
Obviously translating strings to and from Unicode every time you call an
API that takes string parameters adds overhead to your program. It's up
to you to weigh the pros and cons of this approach to suit your
program's requirements.

It is all documented somewhere, sometimes it is just hard to find...
