Matching on quote from say command

[c-hudson]

The do_say function passes double quotes to notify_except in unicode. This makes it hard (impossible?) to match against the double quote produced by do_say in mushcode. I was able to proove the issue by replacing the unicode double quote with a simple escaped double quote in the do_say function. 

Mushcode:
&foo object = ^":say # %1
@set object = monitor

Example:
say foo <-- doesn't match
say foo " bar <-- matches

It should be feasible to match the unicode dquote in the regex, but I'd have to look up the syntax-- so yes, hard.

I'm thinking these should probably regex match on NFKC normalized versions, but that isn't likely a sane default, and is rather nontrivial without libicu...

Alternatively, regex character classes (e.g. [:quote:] or something) might handle this reasonably gracefully.
