Pattern questions

[Zdenek Sekera]

I have this:

if (char =~ '\m[;|<>?:[EMAIL PROTECTED]&*(){}\\_+-[\]/\"]')
  do something
endif

Basically it is checking for all non-alphanumeric chars
(expect '=').

1. how do I include the "'" char?.
   I can't seem to find a proper way.
   (I'd like to keep the patter in enclosed in '...')

2. why when the pattern ends with '+' or '\+' do I get
   an error?
