Missing cjkfont error incorrect

[bjhijmans]

I upgraded to 1.66, and I got the following error that I didn't have before:

 Package polyglossia Error: The current latin roman font does not contain the 
"CJK" script!
(polyglossia)                Please define \cJKfont with \newfontfamily command

I was confused because I did define \cJKfont. Turns out it's now \cjkfont with lowercase letters. Thankfully, I figured it out pretty quickly, but the error could lead people astray.

Thanks for the report. @jspitz it is caused by https://github.com/reutenauer/polyglossia/commit/3ae354adb75176fa5419c0bc7ab35a3e17a5fc6c, can you have a look?

The lowercasing of just the first token in the string was always a bug that forgot about the possibility of acronyms such as CJK (that haven't been used when that code was introduced).

But then, the odd cJK is now in the world, so we could either

• add an alias in case \cjkfont is beeing defined (a bit kludgy, but well) or
• keep things as they are and force users to change their setting (which they need to do now anyway unless we released a hotfix version, which is probably risky given all the heavy code rewrite now underway).

What is your preference?

At least the error message is now correct.

You didn’t ask me, but definitely the latter :-)

Thanks, let's mark this resolved, then.

I agree with Arthur.
