Well it doesn't work, still ... But thanks anyway

What I was trying to say is that there are some 'weird' signs and letters in Vietnamese that the other languages don't have. Everytime I type those letters, they just appear as a '?'. The original character map does not have those characters, and when I add those letters to the Character Map, they appear as a '?' even in then character map.
The part you didn't get was the guide to use the program I sent you(Unikey). Just download the program and type those combination on Win Word, it will give you an idea what do those Vietnamese characters look like.

Can you create a characters' set for me please. I want to translate it to Vietnamese but the X GXT Editor doesn't support my language's characters.
Whenever I type then, they'll just appear in "?". These characters are "a u o d ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? i ? ? ? ? ? ? ? ? ? ? ? ? u ? ? ? ? ? ?". Besides them, the other characters are fine.
Please add those characters so the ? mark won't appear whenever I type them. You can type these characters using program names Unikey. Link: http://www.mediafire.com/?jvmvb2yzvmx4i29
To type those characters, just combine the keyboard keys like 'a+w' -> 'a'; 'o+w' -> 'o'; 'u+w' -> 'u'; 'a+a' -> 'â'; 'o+o' -> 'ô'; 'e+e' -> 'ê'; to get the little mark on the top or bottom of the characters, just use these keys: x,r,f,s,j. Ex: 'a+x' -> 'ã'; 'a+r' -> '?'; 'a+f' -> 'à'; 'a+s' -> 'á'; 'a+j' -> '?'. So if you combine three keys: 'a+w+x' -> '?'. Thank you for helping.

P.S. I'm sorry because those characters appear in here as '?' too so you won't be able to see it. But please try download the program and try it yourself in Microsoft Word and you will see. Thanks again.
