In phpMyAdmin home I can't change collation or other character set todefault.

This collation character set couse problem with website with forign languase (ex:Thai) that fetch data from Mysql to show ex: web board and forum because it default character set is set to latin.

Any one have way to fix this problem.

My solution so far is to put a code in side web page which take time if I have to do this with all of my clients.

Any solution will be very thankful.
