OK, make sure you have:
1, Save file in UTF-8
2, <meta> tag is set to UTF-8
If you are retieving data from DB, make sure, you:
1, Set DB encoding to UTF-8
2, Set table encoding to UTF-8
3, Set field encoding to UTF-8
4, Set connection encoding to UTF-8
When you are doing some operations with string (substr ...) make sur, that you are using mb_functions and you set it to UTF-8.
I think, it helps.
