You may have noticed strange characters (like �) to appear when you try using the PHP substr function with a UTF8 string. The solution is easy, elegant and core PHP: mb_substr
For example mb_substr("Greek χαρακτήρες",0,10,"UTF8"), will return the first 10 UTF8 characters of our UTF8 string.
For more details see the PHP mb_substr manual.

mb_substr("Greek χαρακτήρες",0,10,"UTF8")
or
first:
mb_internal_encoding("UTF-8");
