You are right and I've got confused. This is why I asked how to dump the subject string. I will employ your suggestion from now on for any questionable string and thus will be able to see on my own :) Ze'ev Atlas

The pattern is correct, but the subject is not. The first part,
"abcd\t\n\r\f\a\e9" should match, but then ; will not match \x3b in
EBCDIC because \x3b is an ASCII semicolon. Try changing \3b in the
pattern to \x5e.

Same issue; \123 is \x53 which is ASCII "S".

This won't match. Up to "\x15Z" is is OK, matching "\v*X\v?Y\v+Z", then
\V* will match nothing (because \x15 matches \v) and then \x15 will fail
to match \x0a.

I can see you have turned the \x0a characters in the original subject
into \x15, but you didn't change the one in the pattern.
