It seems this bug is similar to the scenario that happened to Chinese #10291

[cscheid]

I believe @TomBener is correct, and we need the analogous fix to 7b5c247

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

I encountered the same issue when trying to preview an .ipynb file as .pdf.
But, the preview is correctly shown once lang: ja-JP is removed.
