UTF-8 SIM 800

Hi guys! I need help. I have SIM800 and i want to send throught it UTF-8 characters like: á,š,ô,etc... The problem is that when i use SIM.readString() and parse it it give me:

004400690061006B0074006900720069006B0061003A002000E1002C0161002C017E002C013E002C013A

Is there any solution to fix it ?

You would get help quicker if you posted your code and also stated exactly what you want SIM.readString() to give you which it currently isn't. Otherwise it is all just a guessing game.
