The pipe(|) in you regular expression means 'or' right? If so then you
can only have the characters dgHhMmstyf,\-\./:;\\ OR characters in
quotes but not both in the same string so you can have:

dddd, d. MMMM yyyy
OR
'ab$olutN0n$en$e'
But not

dddd, d. MMMM yyyy 'ab$olutN0n$en$e'

Does this make sense?
