I'm concerned about this: catch me on IRC?

No idea what the native OS character set is -- there aren't any mount flags set, so as best I can tell things default to iso8859-1.  Can we just ignore this and fix it if it ever becomes a problem?
The main filesystem is probably all ASCII, so the problem is most likely what's set for the sdcard. On my nexus one, the sdcard is mounted with these flags:

rw,dirsync,nosuid,nodev,noexec,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0

As far as I can tell, this combo (in particular, utf8) means that the kernel will try its best to give us utf8.
Review comments addressed, proper truncate impl added, and the native char conversion now assumes utf-8.
