Subject: [9fans] Equivalent of unix vis(1) with font

Hello,

I was wondering if someone has already done the following for Plan9:

Allowing to render visually non visual characters (controls and blanks)
but not with a vis(1) encoding, but by substituting the font, that is
switching to a font that has, as subfonts, the font already used for
display, but filling supplementary glyphes for the "invisible"
characters, =E0 la EOF, with say a '->|' for a tab, a '|_|' for a space
(it is used by D.E.K. and Silvio Levy' CWEB rendering for strings in
source), a "diagonal" '^@' etc. for controls or whatever?
