unable to send korean alphabet

[randomassusername]

Hi there. I installed the korean language onto the default keyboard of my note 2, if I send a message to myself it shows up fine. However if I send a message to anyone else it just shows up as a bunch of question marks. Ive already changed from gsm keyboard settings, under sms setttigs but still no luck.

I know this person has the language pack installed because they can recieve korean texts from my other friend.

thank yyou for your assistance
