I have experience with M92, but I think the situation with i62HD will be similar.
Some languages are translated better, some worse, some not at all.
If you or some of your friends volunteers to translate the menus, you may have full and good localization into your language. It takes, say, 3-5 hours of work. (I made localization for my language).
If you are willing to do so, ask Booxstor (from this forum) for menu files. And it might appear in next firmware version.
