I am still a little confused how Rockbox deals with long names of other
western char? My understand is that all Rockbox internal funtion use
shortname, which might use different code pages for different languages.
When creating files,like creating playlist, rockbox searches the long name
(unicode name), copies and rewrites to the new record. Then I don't
know why when writing "entry[]" in write_long_name(), Rockbox pad leading
bytes with 0x00. What's inside "name[]" ? Are they all unicode trailing
bytes long name?

Please excuse me if my question is not clear
