Julia puts emphasis on the possible use of non-ASCII symbols in code. Most of supported operators are Unicode characters, some well known mathematical symbols (albeit practically unseen in programming), some are quite obscure. Many standard library functions use Unicode operators along with their AS…

I use them all the time. My keyboard has no α, β, γ, either, but I can type them with one mode key, just as we use the shift key for Uppercase Letters. My keyboard also doesn’t have ñ, é, or ç, but I can type them by hitting another mode key and two additional normal keys. I need these for writing…

You know, I don’t think that’s completely useless. It reminds me of APL, and since, sadly, APL.jl seems to be unmaintained… (The one for dump made me LOL.)

I just want to mention that Japanese (and probably Chinese?) speakers can naturally type Julia’s unicode symbols. We just use the IME : We just type π, α, ∫, ÷, . . . in the same way as we type 漢字 (Chinese characters). The idea is that you can get such conversion as \sigma to σ to work everywhere, …

I find it hugely useful to define a suitably rich keyboard layout so that all those mathematical Unicode symbols actually are on my keyboard: [image] Can package names contain non-ASCII characters? General Usage Total side note, and shameless self-promotion, b…

Yes. For Chinese using 中文代码快速补全 - Visual Studio Marketplace we can avoid switching system IME and type Chinese inside VSCode very fast.

I once found a UNICODE keyboard Nemeio - The customizable e-Ink keyboard Nemeio is a new generation keyboard. You are now totally free to choose how you use your keyboard with Nemeio’s customizable keys that is adapted to your specific needs. […

Unicode gives Julia a level of mathematical expressiveness that most programming languages do not have. For example, below is a cubic-equation solver I wrote that works generically with any AbstractFloat type. ▶ solve_cubic(a::T, b::T, c::T, d::T) where {T<:AbstractFloat}

There are multiple aspects of unicode support. The first is “prosaic” runtime support: This like String handling unicode just fine, the imo nice design decisions on how to handle invalid utf8 strings, indexing via code-units, etc. This makes writing code that deals with unicode not overly painful. …

Not only do I use it, I also probably abuse it, with characters like 𝒞 and 𝐼. But it feels so great.

I’m guessing you don’t like APL.

Do you use Julia's extensive Unicode support?
