AutoCAD 2013 :: Greek Symbol Errors

I have one work station when you insert the greek symbol mew it comes up as M. I tried a few other greek symbols they same to work correctly. I have tried running a repiar, no change. Opening a drawing which has mew in it already makes it display as M

I have tired to insereting it  in diffrent fonts same outcome. I can inseret it onther programs like word, thinking it might be some sort of windows or operating system setting.

copying and pasting mew from word to cad works on all other work stations but this one. We are using Civil3d 2013 on windows 7 machines.

What it might be or a work arounds short of making a block for the symbol from lines.
