It' working.

Test Results:

click https://zh.wikipedia.org/wiki/Special:%E9%9A%8F%E6%9C%BA%E9%A1%B5%E9%9D%A2 (random page), click 10 times, 5 times nstab-main display as "页面", 5 times display as "条目"

In the past it was indeed the allow languageConverter to process interface message, but then I can't remember why it was forbidden.

In browser incognito mode (no cookie, no login ), can't reproduce.

Appear to be correct after several tests here as well.

T229339 also same problem?

thx @Aklapper, and agree with @Dzahn opinion, 403 Forbidden may be more appropriate.

This seems to be a rare case, if an OS support Chinese fonts, it is likely they will have the whole set (Hei, Song, Fangsong, Kai, sometimes Yuan). Windows and macOS and some major linux distributions like Ubuntu certainly do. Anyway, we can always fallback to the default 'cursive' font as specified by the system, fall back to a serif font might also be acceptable in extreme cases. There is also the web font solution, however, I believe that is outside of the scope of this issue.

@Shizhao You're probably right, considering it is a change in the css. It would be preferred to have system-wide css-class to do the job. However, here seems to be a better place to get more technical people involved to determine the best solution.

This seems to be the job of a web browser developer, not mediawiki?

in edit mode, it is not converted.
