It just mean that your system doesn't have necessary locale installed. And that perfectly explain why luit shows all chars, but GoldEd doesn't.
Luit converts them using internal tables to UTF, but GoldEd tries to use en_EN.CP850, which is missing. That's why it doesn't understand that letters with codes > 127 are letters.
You need to install or generate this locale and GoldEd will show those letters! What Linux distribution do you use? Do you need help with locale generation?

Yes. And that's good!

Yep. I meant to run that script without luit in terminal configured for CP850. But you don't need to do that anymore as long as we found root cause already.
