Now you can specify a multibyte-delimiter to cut, which should definitely be possible for the end-user (Fuck POSIX). Looking at GNU/coreutils' cut(1)[0], which basically ignores the difference between characters and bytes, the -n-option and which is bloated as hell, one has to wonder why they are still default. This is insane! Things like this personally keep me motivated to make sbase better every day. [0]: http://git.savannah.gnu.org/gitweb/?p=coreutils.git;a=blob;f=src/cut.c;hb=HEAD NSFW! You have been warned.

The possibility of separating numbers and ranges with a space
|
|
and specifying multibyte delimiters is an extension to that specification.
