This used to be supported, but recently when I am importing translation, I got this message:
Non Latin Unicode characters are temporarily not allowed.
Is there any other workaround?
maybe this: process localization stuff outside curse and only upload the final zip file to curseforge ?
a bit weird, but it works around the bugged localization build process.
Not supporting non-Latin Unicode for importing would be troublesome especially when dealing with Asian languages or Russian.
This was a site setting that was, for some unknown reason, set to enabled. I've turned it off, so you should be able to do these imports now.
