Only if we decide to _always_ try that (under specified circumstances).
If not it will be an optional parameter and the function then will
have a different signature, which will be incompatible with existing
programs using it as a function variable.

The only difference between File* and File*UTF8 functions
(fpc<->Lazarus) is that the UTF8 versions were/are able to handle any
unicodecharacter inside the given path/filename (regardless of you
current Windows codepage).
Otherwise it does not behave different compared to the fpc File*
functions, nor should it.
