Hello,
I've always dreamed about a text editor that will show unicode to me in a slightly more suitable form than what I'm used to. Like a double- width em-dash (assuming fixed width fonts are being used) -- or even a double-width en-dash and a triple-width em-dash -- and visual differentiation between the various invisible characters like no-break space, zero-width joiner, and the half dozen or so extra unicode glyphs that aren't displayed very well in code.
While TextMate's "Show Invisibles" does indeed show no-break space, (most of?) the others remain invisible. And em-dash is rather hard to distinguish from en-dash :)
Has anyone else ever thought such things before? Certainly I think greater editing support for such unicode glyphs would encourage their use (which, at present, seems rather uncommon).
Will
