It's perfectly safe to do this, because on Windows we have internally all file names in UTF-8, and for WINAPI functions we only can use file names in
ANSI CPs (windows-1250, windows-1251, ...) or UNICODE16. File names in these encodings are then automaticaly (inside WINAPI) converted to right
encoding. So if we will always use WINAPI functions with W suffix, we don't need any other encoding than UNICODE.
