Already fixed applets:
Applets which may need unicode handling (more extensive than sanitizing
of filenames in error messages):
ls - work in progress
expand, unexpand - uses unicode_strlen, not scrlen
ash, hush through lineedit - uses unicode_strlen, not scrlen
top - need to sanitize process args
ps - need to sanitize process args
grep egrep fgrep
catv - "display nonprinting chars" - what this could mean for unicode?
last - just line up columns
Unsure, may need fixing:
hostname - do we really want to protect against bad chars in it?
addgroup, adduser, delgroup, deluser
