Launch Character Map app, find Omega, Select, and Copy, and you should 
be able to paste it into any window. 
Post your cmd console code page and locale settings as described and 
maybe someone can help you. 
Or maybe you could check the cmd settings and console docs yourself 
and figure out your own problem. 
Generate cygcheck -svr output and attach to your post as described 
in the problems link below, and one of the project *volunteers* may 
get some time to look at it and be able to help.
