SUMMARY

Okular typewrite (annotation) doesn't show Chinese characters on the page (but
is displayed normally in the popup note).


STEPS TO REPRODUCE
1. Open a PDF file with okular
2. Select "typewriter" annotation tool
3. type any Chinese (e.g. "啊啊啊" (ahhhh)), surrounded with Latin characters (the
second part is not necessary, but useful to test)

OBSERVED RESULT

Chinese characters are not shown.
If surround the Chinese characters with Latin characters, the Latin part is
shown and no space is preserved for Chinese characters. (This rules out font
issues; I also checked the font which is a valid Chinese font, Source Han
Sans.)


EXPECTED RESULT

Chinese characters are displayed correctly.


SOFTWARE/OS VERSIONS
