I'm sorry to disagree

I guess we'll have to agree to differ; but the fact that Perl allows me to replace an (8-bit) character, in the middle of a string of 8-bit characters, with some (random*) wide character is just broken.

"chr()" is - and rightly should be - intended to serve the (dominant) linguistic sense of "character" (what the perl docs call "character semantics")

To what possible end?

When you do my $thing = chr( 12345 ); what does that "character" represent?

Is a Chinese character? Or Sanskrit? Or Cyrillic?

Is it utf-8; utf16; utf32?

Is it big-endian or little-endian?

What if I append another character to it: $thing .= chr( $i );. What does string contain now? Can Perl ever decide what encoding $thing contains?

And the answer to all of those questions is: it is impossible to ever know. Thus, chr's ability to construct wide characters is entirely useless.

So, you break with clearly defined semantics for undefined and undefinable semantics, for what purpose?
