Add shorthands for symbols U+22B6 (Original Of) and U+22B7 (Image Of)

[Slyde-R]

Description

I was not able to properly write equations, because I did not find a way to create the laplace transfrom symbol in typst. In LaTeX they can be created with:

Use Case

Writing equations with typst with the same functionality as LaTeX

my current workaround if someone has a similar issue:

circle.stroked dash circle.filled\
circle.filled dash circle.stroked\

#let o-o = [$circle.stroked dash circle.filled$]
$#o-o$

This must be a very obscure way to denote Laplace transforms. Regardless, these are U+22B6 (Original Of) and U+22B7 (Image Of). You can use them directly with \u{} for the time being.

Thanks a lot for the quick response!

At my university they are used for laplace and fourier transfrom, but appearantly not generally - that's why I couldn't find the unicode for it.

Could you change the title of the issue to something like "Add shorthands for symbols U+22B6 (Original Of) and U+22B7 (Image Of)"?

I'd like to implement this (already implemented a proof of context, in fact), but I'd like to confirm a few things before making a PR.

Firstly, what would be a good syms name for them? Looking at the existing symbols I'm thinking something like originalof and imageof. Secondly, what category to put them into in the source code? I've put them into relations for now in my PoC, is that correct?

Thirdly, is there any need (or, indeed, a possibility) for a shorthand (like typst has for arrows)? I have no idea how these symbols could be represented, so I am leaning towards no, but I'd like to hear a second opinion from someone who knows a bit more than myself.

I guess the alternative names would be origof and imof, since, if compart.com is to be believed, that's how they're named in HTML.

[Enivex]

Just original and image would make the most sense. You shouldn't add shorthands.
