Where can I change the topics character count.

General>Messages & emails>Configuration
Under the topics frame,
Topics title length : Change the values.

Hope it helps.

Its already at max which is 255. I want to change the actual post character count.

Characters in the messages: 15 999 characters (Including spaces)

Some Limits of forumotion.
