Hi all My host Blue Host uprated mysql 5.1.41 last night last night. 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 same problem and is able to fix it. Please share what you did. 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. Thanks
