It seems this bug is similar to the scenario that happened to Chinese https://github.com/quarto-dev/quarto-cli/issues/10291

[cscheid]

I believe @TomBener is correct, and we need the analogous fix to https://github.com/quarto-dev/quarto-cli/commit/7b5c2477d12c84a0ddc9ca11e6b492cdac21f616

But, more generally, I subscribe to the "there's only three numbers in software engineering: 0, 1, and infinity" theory. So I don't believe this is only needed for simplified chinese and japanese; other writing systems probably need addressing as well, and we should come up with a more general fix.

Totally. We just need a way to know which one needs it or which don't. Or we just need to revert the feature in a way that we don't try to install it automatically and let user do it if there is a real problem.

I'll compare with tinytex R package because we don't have this issue, and probably because we don't try to install automatically a package if we detect this hyphen message in the log file.

there is a list of languages that support hypenation at https://github.com/hyphenation/tex-hyphen/blob/master/data/language-codes/tex-languages.txt

maybe that helps

[cderv]

Definitely helpful ! This can be a good base for us, to only try installing for one of those known packages
