If I try to write this (there are double back ticks around the latex expressions but can make it show here)

`Select map projection. lon\_0 \yen The following character determines det`

I get. Note that the yen symbol is rendered right but not the subscript.  
How do people write sub/super scripts in docs (Documenter here)?

Why did you escape the `_`? Without that it works as expected for me.

Well because I saw it [here (julia docs)](https://docs.julialang.org/en/v1/stdlib/Markdown/index.html#%5CLaTeX-1), that’s how it works on REPL and because that worked with the `\yen` case. But you are right, no escaping works (thought I had tried that too)

I can’t find anything about subscripts on that page.

`\yen` is a latex command so not sure how that relates to `_`.

\_0 is a latex command too. We can find it in that table, though it’s not obvious because it’s a very long table. There is one row that says

U+02080 ₀ \_0 Subscript Zero / Subscript Digit Zero

Yea, and it works, but you added an additional `\` that breaks it.

Did you mean to link to [Unicode Input · The Julia Language](https://docs.julialang.org/en/v1/manual/unicode-input/) then? That is for input in the REPL which is not latex.

I added the \ because it’s in that page (it was removed in the copy paste).  
My point is that if `\yen` works, it makes all the sense to expect that `\_0` works too (considering what we see in that table, be it for REPL only or not)

But that table is for tab completions in the REPL, and between ` ` `` you should write latex. The case for `\yen` just happens to coincide.

OK, bad luck in my picked example then. Anyway, I got the subscripts which the important.  
Thanks.
