OK... some progress.
At least I've discovered how to change the settings so that it reads the 15 supported languages properly.
I just needed to find the right place to make the changes..... D'OH....
Now it's all in Russian, so lets hope I can figure out what to press to get it back to English again.
EDIT:
PHEW... that was interesting! Trying to navigate menu systems in Russian is a skill that I don't have. Fortunately I made the right guesses without stuffing anything up along the way.
The built in language choices are the 15 I mentioned plus Romanian.
With the language set to English it only gets some of the lines in your document correct. Some lines then have a few errors ( a sprinkling of ??? marks), but Russian, being a completely different script shows as all ????????s
However, once I change the setting the menu displays are fully functional, including Russian. At least it all looks OK - I don't read Russian.
So it seems that it can handle the languages one at a time, but won't mix different languages and display them all correctly - unless they use similar sets of symbols - which seems fair enough.
I'm not a linguist, so does that set look like it would be usable for a good spread of languages or are there any major omissions?
Hope that's useful anyway.
