[^[:ascii:] or [[:^ascii:]] ??
How about [^:ascii:]?
The part of the message you snipped in your quoting answers this. Here it is again, with John W. Krahn's comments:
perldoc perlre on 5.8.0 says that [:ascii:] should match any ascii character and [:^ascii:] is the negate version.
If I do =~m/[:^ascii:]/ or [:ascii:] on astring that is 'hi' it
That character class matches the characters 'a', 'c', 'i', 's', ':' or '^' and 'hi' contains the character 'i' so it returns true.
returns true each way, so I believe it says the [] are part of [::] conbstruct which I think means you have to have[[:class:]]
Yes.
