Great info. The last part about the sys.stdout not working everywhere is a bit troubling. But For now, I am just gonna add a try statement as stated in the previous message. Thanks again,
PS... The software company I work for has a version that runs on Unix/Linux so I am awaiting a new laptop with which to employ Linux! I cant wait to get back to my roots. Debian and Fluxbox.... could there be a better working environment?

Yup, CP437 doesn't support the Χ character. You will have to use a terminal that
can accept a full-Unicode encoding like UTF-8 and a font that has the relevant
characters. Most of the modern terminal emulators for Linux et al. are capable
of UTF-8. On Windows, you may be out of luck. I don't know of any
fully-Unicode-capable terminal. Google tells me that cmd.exe takes a /U argument
that should put it in Unicode mode, but that doesn't change anything for me.
I also ran into a case where sys.stdout.encoding is None, so my solution is not
as robust as I thought.
If you use something else for your interpreter shell like IDLE, it is possible
that it supports Unicode. sys.stdout.encoding may not be set appropriately, though.
