If we do go for a change, we should use sizeof(wchart) as basis for the new default - on all platforms that provide a wchart type. I'd be -1 on that. Sizeof(wchart) is 4 on OSX, but all non-Unix API's that deal with Unicode text use ucs16.

Is that true for non-Carbon APIs as well ?

This is what I found on the web (in summary):

Apple chose to go with UTF-16 at about the same time as Microsoft did and used sizeof(wchar_t) == 2 for Mac OS. When they moved to Mac OS X, they switched wchar_t to sizeof(wchar_t) == 4.
