Chaos,
I'm sorry but the Triumph doest not support Unicode for text or mms here is a list of supported formats
ISO-10646-UCS-2
ISO-8859-1
US-ASCII
UTF-8

My plan is to hopefully use this the UAProf which is supported by cyanogenmod source code to get our MMS allowing for larger format as it supports higher quality than we are using now.
Still been battling MMS but right now I am battling a dead computer, my fans are spinning like crazy and I'm currently running a memtest86 to see if its bad ram, next CPU test and then hard drive. Hopefully its nothing serious.
