I would love to see a document (one per editor) that describes the
Unicode characters in use and how to make them. The Set implementation
in Pugs uses (at last count) 20 different Unicode characters as
operators.
I have updated the unicode quickref, and started a Perlmonks discussion
node for this to be explored - see
http://www.perlmonks.org/index.pl?node_id=462246
As I replied on Perlmonks, it would be more helpful if the Compose
keys were listed and not just the ASCII versions. Plus, a quick primer
on how to enable Unicode in your favorite editor. I don't know about
Emacs, but the Vim documentation on multibyte is difficult to work
with, at best.
Well, :help digraph isn't particularly bad, though the included table only
covers latin-1. The canonical source is RFC1345. But I've attached a patch
for the set symbols that have them.
Thanks,
Rob
