Re: problems packing 8 bit data

After reviewing your response, and the testing I've been doing in between,I have come to the conclusion, that I think I agree with you.

The string is correct, its the output interpretation that needs to be affected. The binmode does alter the resultant output.

Now if someone could just explain what translation is really going on here in this particular bit pattern example.
ie. a 0x80 is actually represented as a 0xc2 0x80, because ???.

As John M. Dlugosz says above, it is the UTF-8 encoding of the (ISO-8859-1) string.	[reply]

...because your copy of perl has been built with perlIO, and STDOUT has--by default I assume as you don't know about it--IO layer :utf enabled. This means that characters above the 7-bit ascii limit are converted to their utf (16-bit) representation on output. Using binmode on STDOUT removes this layer and so the convertion is not done. Looking at perldelta, I cannot find anything to indicate that STDOUT would be opened :utf by default, but if you aren't doing anything to enable this yourself, I assume it must be? See the section of Perldelta headed "PerlIO is now the default" and follow the various links close to the bottom of the section for more information. Examine what is said, not who speaks.
