Player: check chat length check with strlen() before mb_strlen()
mb_strlen() is O(n), whereas strlen() is O(1). If we receive very large chat messages (e.g. 2 MB), mb_strlen() will take a very long time to return a result (around 8ms on my machine).
Since the max size of a UTF-8 character is 4 bytes (according to standard), we can use strlen() with 4x the char limit to gate it and prevent this from happening.
