Hi everyone, I'm a bit of noob, so perhaps this question has already been answered... but I looked everywhere and didn't find the answer.
I am using the new openinkpot snapshot (downloaded last night) on my Hanlin Bebook. So far I think it is fantastic, and would like to congratulate all of you for the great work.
I was so pleased with it, that I flashed it on, so am not running the live version from an SD card.
I mostly read in English. I've downloaded some RSS feeds, converted to MOBI format with Calibre, and when I open them there are some random characters scattered throughout the text, such as boxes, the "TM" sign, a character box etc...
I suspect that the encoding is wrong, and I need to force it manually to English. Is this possible? I saw that someone had suggested modifying the /home/.FBReader/books.xml file, but I unfortunately don't know how to do this.
I tried reading the files as an EPUB file, but then the index doesn't work (ie. once I select where I want to navigate to, the page flashes but it remains stuck at the index.
Regardless, I would prefer using the MOBI format, so if anyone has any suggestions about how to solve the character issue I would be very appreciative.

THanks,
