Language encoding problem

when I was programming localy at my pc with xampp and joomla, whatever was written in greek was read correctly. but when I uploaded the site here, greek letters are only ‘?’ now.
see: oldradiorepairs.bplaced.net/index.php/forum.html
the only thing I found is greek translation for joomla, but not greek encoding support. I changed the table collation to utf8_general_ci (originally latin) to every table of the forum component (after I installed it), but the problem persists.

No, the problem is not the MySQL-Table …
the problem ist the charset, by your site it is UTF8…
I don’t know, which charset qou need for greek…
anyqay, it helps you, when you try the php function header

you have to change the charset (in this example"iso-8859-1")

Update: by the windows-systems it can be the charset “windows-1253” - but only on windows…
Update: So, i think, the official standard is “iso-8859-7”…

I figured out that it’s a component problem, as I can write in greek submiting an article in front-end or composing another in back-end! Thanks for your replies!

Maybe the character encoding for the connection between php and mysql is not negotiated correctly.

Yeah, that was it! I fixed it today! I needed to change the collation in myphpadmin to utf8_general_ci.
