Non-ascii character warnings in epubcheck

Hi folks,

 

While going over the updates to epubcheck, I noticed that it still emits
warnings if non-ascii characters are found in file names. I've proposed
changing the warning to a usage message as it is only related to a note
about old processing tools.[1] Otherwise, we're going to be blocking a lot
of people from using these characters given vendor restrictions on warnings.

 

If you have a strong opinion against this change, though, (or for it) please
add a comment to the issue.

Thanks,
