Hmmmmm, here lies the catch. According to UTC, you need to keep processing
the UNIX filenames as BINARY data. And, also according to UTC, any UTF-8
function is allowed to reject invalid sequences. Basically, you are not
supposed to use strcpy to process filenames.
Well, I just hope noone will listen to them and modify strcpy and strchr to
validate the data when running in UTF-8 locale and start signalling
something (really, where and how?!). The two statements from UTC don't make
sense when put together. Unless we are really expected to start building
everything from scratch.

Not by definition. But if it would help the users since it would simplify
the transition, then why not?
