Enable options and features which are not essential.
Select this only if you plan to use busybox on full-blown
compiler other than gcc.
If you do use gcc, this option may needlessly increase code size.

+ For the most part, busybox requires only POSIX compatibility

All BusyBox applets will show more verbose help messages when

help
This makes various applets aware that one byte is not
one character on screen.
Probably by the time when busybox will be fully Unicode-clean,
other encodings will be mainly of historic interest.

+ With this option on, Unicode support is implemented using libc
