I have 2 problem at the same time which i solve them but when i fix one of them the other problem raise again, one of them is character encoding when i insert some sentence, db shows Ş,İ,ş,ı characters as a "?" i solved this problem putting the useUnicode=yes&characterEncoding=utf8
jdbc:mysql://localhost:3306/Wiki?useUnicode=yes&**characterEncoding=utf8**&&user=root&password=
But my second problem,
Incorrect string value: '\xF0\x90\x8C\xB2\xF0\x90...' for column 'w_text' at row 1
When i remove the characterEncoding=utf8 the problem is resolved but my first problem raise again.
By the way i change the db character group as utf8mb4_general_ci
Any idea for this?
