+Unicode work needed:
+
+Unicode support uses libc multibyte functions if LOCALE_SUPPORT is on
+(in this case, the code will also support many more encodings),
+or uses a limited subset of re-implemented multibyte functions
+which only understand "one byte == one char" and unicode.
+This is useful if you build against uclibc with locale support disabled.
+
+Unicode-dependent applets must call check_unicode_in_env() when they
+begin executing.
+
+Applet code may conditionalize on FEATURE_ASSUME_UNICODE
+in order to use more efficient code if unicode support is not requested.
+
+Available functions (if you need more, implement them in libbb/unicode.c
+so that they work without LOCALE_SUPPORT too):
+
+int bb_mbstrlen(str) - multibyte-aware strlen
+size_t mbstowcs(wdest, src, n)
+size_t wcstombs(dest, wsrc, n)
+size_t wcrtomb(str, wc, wstate)
+int iswspace(wc)
+int iswalnum(wc)
+int iswpunct(wc)
+
+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
+
+Probably needs some specialized work:
