Good news everyone! I've written a small library that offers various transformations of text to special Unicode characters. The most prominent one is the latexstring to latexunicode: "\\itA \\in \\bbR^{nxn}, \\bfv \\in \\bbR^n, \\lambda_i \\in \\bbR: \\itA\\bfv = \\lambda_i\\bfv"
==> "𝐴 ∈ ℝⁿˣⁿ, 𝐯 ∈ ℝⁿ, λᵢ ∈ ℝ: 𝐴𝐯 = λᵢ𝐯" It doesn't support the whole range of latex, but I hope it will be enough for simple formulas. I will obviously use this library for latex label support in GLVisualize, but I hope that this library can also be usable in other contexts! (REPL latex renderer?) Enjoy with a simple Pkg.add("UnicodeFun") (since its freshly registered, a Pkg.update() might be needed) Please feel free to report latex strings that are not working, or help adding new transformations! :) Best, Simon


thanks. I wish I could get the \frac symbol is there possible to
make it ?

The best adhoc solution I could find looks like this: 1̲2̲ ̲/̲ ̲2̲0̲ 200 So not impossible... I'll see how we can integrate this Am Mittwoch, 28.

I added the to_fraction function: to_fraction("α² ⋅ α²⁺³ ≡ α⁷", " ℝ: 𝐴𝐯 = λᵢ𝐯") > α̲²̲ ̲⋅̲ ̲α̲²̲⁺̲³̲ ̲≡̲ ̲α̲⁷̲ ℝ: 𝐴𝐯 = λᵢ𝐯 https://github.com/SimonDanisch/UnicodeFun.jl/pull/3 But I won't have time to add this to the to_ latex function, since it's a bit more involved with the line break.

That's the short form which works with sub/superscript and will create something like: to_fraction("a123", 392) == "ᵃ⁻¹²³⁄₃₉₂"
For the newline version try: to_fraction_nl("α² ⋅ α²⁺³ ≡ α⁷", " ℝ: 𝐴𝐯 = λᵢ𝐯") I really need to rework the names and documentation ;)


what about the other direction? It would be a sick to write symbolic code for SymEngine or SymPy in that unicode form, and have it convert to the appropriate code.

Sounds fun! Since I won't use this, this would need to wait until the next procrastination attack. But feel free to submit a PR. Should be relatively straight forward :)
