Needs Experts ideas on this strange problem

[ARP]

Hello All,

I have a strange problem I can't send any PM to any member if he has some unreadable symbols

Example :
ทŁ ....etc

But if i open admincp and edit to any of this users profiles and save without any changes the PM's to this members works fine

So Is there any sql or any thing I can do to update all my members like the same SQL in admincp edit users

--------------- Added [DATE]1256933188[/DATE] at [TIME]1256933188[/TIME] ---------------

I have tried all the update counters and it's still didn't work
it's working only of i edit the member from admincp and click on save without any change

--------------- Added [DATE]1256988970[/DATE] at [TIME]1256988970[/TIME] ---------------

That's strange no one know what the SQL query to update the member like the edit user in admincp ?
