Some people have a perennial problem with unicode in source files, and would prefer to simply never deal with that. We have two interesting precedents inside the julia language to deal with that: String literals permit unicode escapes, like "\u00b5 is a greek letter". In other words, unicode hate…

Ah, sorry. You must be right. It looks like a fallback has been used in this case… Maybe Iosevka does not support :spaghetti: after all?

Pity - I thought it might have been some unusual Linear Algebra operator that I’d not heard of and omitted by mistake… :grinning:

Yes, I misspoke. I just looking at my Emacs config and realized that I set up Noto Color Emoji as a fallback ages ago. Generally, I don’t think fonts should support every single UTF8 glyph under the sun, that’s why we have fallbacks.

[image] mbauman: How would you write μm? Yes, this is an issue Ialso came up with when sketching the necessary changes in JuliaSyntax.jl: For tokens that contain both escaped and unescaped chars, one needs separators. A simple one could be \\:\mu:m, i.e. \\ opens a trigraph-sequence; if foll…

[image] foobar_lv2: I am somewhat astounded by the kind of push-back I’m receiving here. [image] foobar_lv2: A simple one could be \\:\mu:m well… anyway, I don’t think comparisons to latex are very useful, since nobody but the author reads latex source code, but many people read Julia…

[image] foobar_lv2: Can we reasonably address the issues of unicode-in-source haters? By helping these people like me with their needs, not by depriving others of the things they love in julia? (however misguided I personally might think α in code is, that would be a very different discussion, …

[image] foobar_lv2: I am advocating for learning from the excellent user-experience of TeX You’re not, really, because there’s a mismatch between source files in Julia, a programming language, and in TeX, a typesetting system. The TEX file isn’t the endgame, it’s intended to be rendered into …

[image] foobar_lv2: I am advocating for learning from the excellent user-experience of TeX I think this must be the first time I’ve ever heard the user-experience of TeX (or LaTeX) being called ‘excellent’. I use LaTeX everywhere, if I can (even our wedding table layout plan(!)), because TeX …

[image] DNF: And I should definitely change my setup so I can use unicode in the LaTeX source code XeTeX?

Yes, I know, I just have to get it done.
