Hmm, interesting! But why is this better than having separate API functions for UTF-8 and thus avoid the risk altogether?
FWIW, filenames in my application are often not "readable" but a combination of letters, numbers and symbols which make up an identifier. It's quite possible that these will also never clash, but why take the chance?
Best regards,
Mikael

One way to deal with this is to make the UTF-8->UTF-16 converter
translate any errors in UTF-8 encoding by looking up each byte in the
error in the current code page (or just hard-code CP1252) and use
that. This allows it to continue to work with code that has
extended-ASCII filenames as well as UTF-8 (except for the very low
chance that the filename happens to have the bytes arranged such that
they are a valid UTF-8 character, this is almost impossible for a
human-readable name in an extended ASCII). IMHO 90% of the problems
with I18N is that programmers don't do this, preventing a seamless
transition to UTF-8 where you can gradually migrate your text.

In my application I currently have code in place to ensure that the file names are encoded in the current codepage. I guess I will now have to first check which cairo version the user has, and then convert as needed? Are all applications expected to do this?
