--- Comment #2 from BugSeeker rikul@inbox.ru --- Suggestion in Comment 1 is not working.
The bug relates to a broken FontLink mechanism for Japanese. With FontLink, Japanese characters are recognized but render incorrectly, appearing messy. This seems to be due to a missing settings update or initialization.
When using FontSubstitutes, the characters display clearly.
