+Unicode work needed:
+
+Applets which only need to align columns on screen correctly:
+
+ls - already done, use source as an example
+df
+dumpleases
+lsmod
+
+Applets which need to account for Unicode chars
+while processing the output:
+
+[un]expand
+fold
+man
+watch
+cut (-b and -c are currently the same, needs fixing)
+
+These applets need to ensure that unicode input
+is handled correctly (say, <unicode><backspace> sequence):
+
+getty, login
+rm -i
+unzip (overwrite prompt)
+
+Viewers/editors are more difficult (many cases to get right).
+libbb/lineedit.c is an example how to do it:
+
+less, most, ed, vi
+awk
+[ef]grep
+sed
