in thread Jargon relating to Perl strings

As you see, Iíve completely dodged the whole UTF8-flag thing. By giving definititions of string components for just code points alone (and graphemes built up of code points) as the fundamental contituent string components, not about bytes and characters, I (try to) avoid the thornier issues.
And by avoiding the UTF-8 flag/encoding, you're creating confusion. $x = "\xBB"; utf8::upgrade($x);. Now it's not clear to me whether you consider $x to by a byte or not. One can encode 0xBB in 8 bits (and it is encoded in 8 bits in LATIN-1), but its Unicode encoding uses 16. So, if you say A code point that fits within 8 bits is sometimes called a byte, that's ambiguous. Whether or not the code point 0xBB fits in 8 bits depends on its encoding.

[Corion]: Hi choroba! I'm somewhat fond of this picture - I think it is Breaking Bad-style even though I haven't watched the series at all ;)
[Corion]: Hmmm - and now that I look at it, the gallery I'm using doesn't produce non-Javascript compatible links in the sense that hotlinking to an image will only work for Javascript enabled...
[Corion]: On the other hand, maybe supporting non-Javascript isn't that much a priority, and I'm not exactly sure how I could make it work for both kinds of browsers without server-side magic
