Arrowchat + Vbulletin encoding issue

[marc276]

I've vbulletin 4.2.0, where arabic usernames are written to mysql in wrong chars but vb displays them correctly.

last week I added arrowchat, where they display them like how they are written into database.

Their support don't want to support me in this unless I give them FULL access to my database + full access to the file manager (to fix encoding in arrowchat files)

I asked why they want that, and provided FTP to their arrowchat directory but refused to help without accessing my database and vb files !!!!!

anyone faces such issue and know how to fix it? + I started to have doubts in arrowchat support who are not reasonable and asking for full access to a customer db ! (the weirdest request ever)
