Some additional details: the text is in polish, the characters that can be seen in the picture are what you get when you take UTF-8 encoded text and interpret it as cp1250 (single byte encoding, used for polish locale on Windows). The original text was "Zmiana tytułu stron z SSO".

Korean has same issue with UTF-8 encoding.

My problem has been resolved by setting encoding (UTF-8) for virtual machine for JIRA.
Refer to below post if you can read Korean:

Yeah, @heeyeonwiz's way is really works for me!
Just add:
-Dfile.encoding=UTF-8
-Dsun.jnu.encoding=UTF-8
into JVM_SUPPORT_RECOMMENDED_ARGS parameter in setenv.sh on Linux. Or into Jira service startup options on Windows.
