Additionally, as the GNU philosophy shifts information away from manual pages (and uses tools such as info), usage information is more extensive.
Unfortunately, even a latest forthcoming coreutils version 6.10 does not properly support multibyte encodings, such as UTF-8. For example, command output from echo "abcабв" | tr [:lower:] [:upper:] in ru_RU.UTF-8 locale should produce ABCАБВ, but with GNU coreutils result is ABCабв. Thus, tr works well with ascii part of the string, but fails to operate with multibyte characters абв.
The Debian package coreutils 5.2.1-2 contains these programs.
