Last night BlueHost my host decided to upgrade mysql from 5.0 to 5.1.41. After upgrading, Khmer Unicode is not working on my forum any more. I called them and they could not figure out to fix it. So I wanted to see if anybody here has the experience. I checked the character set and collation on the database and tables, they are OK set to UTF-8. Appreciate any tips or hints on this.
