specify unicode characters on command line

[anthony]

At this time you can not specify \u escapes in IM, It just does not understand them sorry.

Though if your shell scripting allows you can use UFT-8 strings directly, though unless you are doing direct 'non-shell-parsed' calls to command from a API like perl, that will probably not work.

The better method to handle utf-8 binary text is either from a file or stdin using the '@' string escape.

Converting unicodes into utf-8 is best done though other programs, like the GNU printf (under linux) or the perl printf.

See IM Examples.
