when you pass a numeric value greater than 255 to chr, it must return a wide character.
There is no "must" about it. It should be the case that unless I specifically ask for Unicrap, characters should be assumed to be 8-bits.
I'm afraid I don't quite understand the reason(s) for what happens when the "use bytes" pragma is added -- if I've done it right, the only difference is to eliminate the warning message about the "wrapped character in unpack"
You're right. It does just enough to lull you into a false sense of security; then sneaks around behind and kicks you in the nuts!
Is it the case that you got the particular pattern of zeros and ones you expected, and were just complaining about the warning message?)
No. I wanted the shift to discard the high bit, as it does with integers:
Unfortunately, Unicrap (and Perl's implementation of Unicrap) conspire such that you can no longer rely upon simple byte semantics.
The idea that a string (a good old array of bytes) can suddenly contain a random Unicrap character in a program that doesn't (and doesn't want to) use any Unicrap, is a farce!
