Unicode Commands

I've been working with unicode characters lately and found myself wishing I had a decent text editor that would let me map arbitrary unicode symbols to some keystroke. Tcl, more than almost any other language but maybe APL, would benefit from easy access to this feature. I found myself wanting to use, for example, the lower right pencil as an alias for "set" - it seems very appropriate

  interp alias {} ✎ {} set

✎ x 1

The trigram for "Heaven" ☰ or Square With Horizontal Fill ▤ might be "list"

list insert: ▤ ⎀

Using single symbols, we could shrink ensembles by eliding spaces: ▤⎀

list copy for lrange: ▤⎘

Any other ideas? =)
