API changes

[n7s]

SU.utf8char() was deprecated in SILE v0.11.0. Please use luautf8.char() instead.

Where is SU.utf8char() used? I see two occurrences of SU.utf8charfromcodepoint() in classes/fontproof.lua, but not SU.utf8char().

I also unable to see any usages of this left either in fontproof or SILE itself. I'd be happy to help fix anything that needs it but this seems to be a non-issue. Unless maybe the problem is in SILE itself not being the latest release? I seem to recall this still needs updating to v0.12.0, perhaps the error is being thrown relative to an old version of SILE being used.

Sorry, my mistake, it turns out these warnings are coming from fontproof but from the classes shipping inside smith. I can confirm we are running the lastest SILE and fontproof versions. I got confused looking through the logs of our font builds and mixed up the results.

No problem, glad it got tracked down. If you need help porting deprecated bits to new APIs please feel free to ask. I typically test deprecations on my own past projects but that doesn't always catch edge cases where the replacement isn't clear.
