Texts sometimes error if the language is Chinese

This issue is invalid. Attach your crash-report so we can diagnose your problem!

... except this ticket isn't about a crash.

Then I don't understand its description. The affected version is MC 1.13-pre7 and he says MC 1.13-pre6?

"some buttons which make 1.13-pre6 crash" probably refers to this bug and its duplicates: MC-132665

Then, it's incomplete. We can't suppose what the reporter means, (s)he has to describe it.

Copy&Paste from the summary: "The description should contain details of the problem and how to reproduce it, so that we can more easily track down the problem and try to fix it."

Confirmed.

Steps to reproduce:

1. Set language to Chinese.

2. Click a few buttons. Some Chinese characters won't show up correctly.

3. If you want to, enter a world and try to write into the chat. Some Latin characters as well as some punctuation won't show up correctly.

OK, can reproduce now, I attach a screenshot.
