Why is this RE
^[[:print:]]
not equivalent to this RE?
^.
The RE ^[[:print:]] finds blank lines (^$), but I'm confused as to why.
(2[Bb]|[^2].|.[^Bb])
That is the question.

I don't know why either.
[[:print:]] seems to match TAB [\x09], LF [\x0A], VT [\x0B], FF [\x0C] and CR [\x0D].
I believe that is wrong, and that (of ASCII characters) [[:print:]] should only match space [\x20] and graphic characters [\x21-\x7E].

It’s déjà vu all over again
I just now rediscovered this issue
Lesson learned is to use [\x20-\x7E] rather than [[:print:]]
(2[Bb]|[^2].|.[^Bb])
That is the question.
