I have a client that need a site with german language.
German has character like δί and others.
But when i use PHP, it can't show up. I have to change it to html ascii like äß
So, when people view source this site, it will show äß, and not δί
i have tried to use html_entity_decode to convert äß to δί.
it works fine at my local server. But when i upload to my server, it fail. The tag for äß can't conver to δί.

Can any one help me please for this case? Or is there a simple way to use german character at my web with PHP file?
