in reply to "ISO-8859-1 0x80-0xFF" and chr()
1. chr() returns characeter not bytes.(silly me)
While "bytes" and "characters" is a useful mental image, it's not always correct. The operation defines the context. For example uc interprets a string as text no matter what, whereas print interprets a string as bytes (if it can)
The real problem is that the byte 0xe9 cannot be decoded as UTF-8, because it isn't UTF-8. Either do nothing with it (which works on sufficiently modern perls), or decode it as Latin-1, because Latin-1 (aka ISO-8859-1) maps each byte exactly to the same codepoint number.
Note that instead of calling encode() on each output string, you can also set an IO layer which does it automatically:
binmode STDOUT, ':encoding(UTF-8)';
Or on the command line, you can set that up with the -C option:
$ perl -CS -wE 'say chr hex "E9"' é
