Non-Latin Alphabet

I recently tried to describe some wording on a stamp which involved the use of Greek alphabet, however the text came out only as alt-codes and not as Greek letters. Did I do something wrong or is the systems set up to accept only Latin alphabet? Here's an example (abg) #945;#946;#947;.
Thanks in advance.

If you use the character map in windows Start > All Programs > Accessories > System Tools you should get something like this:

#966;#937;

You are right, BeeSee, the Greek looks OK in the preview, however it does not work in the actual post. Nothing seems to work.

I have a virtual Greek keyboard installed so I can type regularly rather than letter by letter from the Character Map. I hope the powers that be in SCF see my original question and give me some idea. What I am thinking if the need arises again is to create an image with the Greek text and post it as a jpeg. Here's an example:
