Problem with UTF-8 compatability - Joomla! Forum - community, help and support

hi there! i'm using k2 extension handle articles , purposes can serve.

i wanted change date , weekday names edited '\language\en-gb\en-gb.ini' file. replaced monday, tuesday, january, february , forth icelandic counterparts.when saved, special characters became 'diamond question mark'.

i tried adding

code: select all

ini_set('default_charset', 'utf-8')

top of en-gb.ini file, tried

code: select all

ini_set('mbstring.internal_encoding','utf-8');
ini_set('mbstring.func_overload',7);
header('content-type: text/html; charset=utf-8');

when that, instead of printing out e.g. "date: n�v" (should nóv) prints "date: november_short" name of tag contains "nóv"
