iTunes/iPod nano & chinese song names [please help]

i own an iPod nano 4gb.

first question is is there a setting i can choose (either in iTunes or the iPod nano itself) to make the on-screen iPod nano text appear larger than the default? anyone that has chinese songs with chinese characters will notice that the font as compared to english text is relatively lighter (not as bold). hence, it is harder to read.

second question concerns chinese music. all my songs are chinese and the song names, artist names, album names etc are in chinese characters. those files that appear with chinese characters by default on Windows appear fine on the iPod nano as well. however, most of my songs require a program called NJStar Communicator (www.njstar.com) to display the chinese characters - those that have chinese music should know what i'm talking about. without NJStar, the names just appear as random symbols in Windows. the problem is, all of the songs that require NJStar appear on the iPod nano as symbols despite the fact that they appear as chinese characters on iTunes when NJStar is turned ON. when NJStar is turned OFF, the names are just displayed as symbols on iTunes. irregardless of whether i update my iPod nano when NJStar is on or off, the names remain as symbols on the iPod nano and i was just wondering if anyone knows how i can fix this or perhaps it's just tough cookies XD

any information is much appreciated,

many thanks.
