in reply to Better rewrite of multiple ifs

interestingly to note, capital greek letters in your PostScriptum look okay, whereas none of ordinary greek text looks good. Each letter is replaced by some accented character.

Soomething with importance of your PS note! :):):)
addition Didn't you entered greek letters at bottom as something like Σ ?
May be it worth re-encoding entire your script in such a way, in one go?
