unsupported non-latin languages

Greetings,
I have completed the greek translation for Spagobi UI, but there is a problem in its' appearance and functionality.
When the translation is coded with utf-8 encoding, it doesn't appear right.
However, when I use html character entities for the greek characters, they appear OK. Well, I don't have to mention that converting non-latin utf8 characters into html entities in a translation file is NOT a good programming practice, do I?!

For example:
Greek text using UTF-8 encoding that does not appear well in spagobi:
100=Γενικό Σφάλμα
Greek text using character entities that appears well in spagobi:
(i'm using spaces after the "#" because the forum engine also alters html entities into greek characters automatically)

I imagine that there is a place where language files are manipulated inside the code, but I can't seem to be able to find it and fix it.
I have tried the tips given on this topic, as well as on the Internationalization wiki in spagobi, but with no result.

Has anyone else dealt with this problem, or does anyone know how to fix it?

Thanks in advance for your time.

So you are adding a new language in the locales, aren’t you?
Try to take a look at the French translation. It uses non latin characters using the utf8 encoding. For example 'Enregistrer le mod\u00E8le'. So take a look at fr.js.
