Another dum dum Unicode idea is having multiple code points with identical glyphs.
Rule of thumb: two Unicode sequences that look identical when printed should consist of the same code points.

If anything, Unicode should have had more disambiguated characters. Han unification was a mistake, and lower case dotted Turkish i and upper case dotless Turkish I should exist so that toUpper and toLower didn't need to know/guess at a locale to work correctly.
Characters should not have invisible semantics.
So you think that the letters in the Greek and Cyrillic alphabets which are printed identically to the Latin A should not exist?
And, for example, Greek words containing this letter should be encoded with a mix of Latin and Greek characters?

Yes. Unicode should not be about semantic meaning, it should be about the visual. Like text in a book.

Yup. Consider a printed book. How can you tell if a letter is a Greek letter or a Latin letter?
Those Unicode homonyms are a solution looking for a problem.

Do you think 1, l and I should be encoded as the same character, or does this logic only extend to characters pesky foreigners use.

Unicode is about semantics not appearance. If you don't need semantics then use something different.

I can absolutely tell Cyrillic k from the lating к and latin u from the Cyrillic и.
>should not be about semantic meaning,
It's always better to be able to preserve more information in a text and not less.

What about numbers? Would they be assigned to arabic only? I guess someone will be offended by that.
While at it we could also unify I, | and l. It's too confusing sometimes.

They render differently, so it's not a problem.
As far as I know, glyphs are determined by the font and rendering engine. They're not in the Unicode standard.
Fraktur (font) and italic (rendering) are in the Unicode standard, although Hackernews will not render them. (I suspect that the Hackernews software filters out the nuttier Unicode stuff.)
I don't think that would help much. There are also characters which are similar but not the same and I don't think humans can spot the differences unless they are actively looking for them which most of the time people are not. If only one of two glyphs which are similar appear in the text nobody would likely notice, expectation bias will fuck you over.
I wonder how anybody got by with printed books.
