Support for Croatian characters (Latin-2)?

[Luka_Tomislav_Galić]

Hello,

can anyone help me with the proper display of Croatian characters? We're having issues with letters such as č and đ as they are displaying as question marks.

I've changed the database character set, and only that, following this guide:

https://confluence.atlassian.com/kb/how-to-fix-the-collation-and-character-set-of-a-mysql-database-744326173.html

But Confluence failed to start properly using utf8mb4 character set.

Thanks in advance!
