Files with `§` in title not recognized

[danymat]

I'm currently using the § character to add structure to my ZK (§§, §1, etc). I think this character is not recognized by neuron

Steps to reproduce

1. Create a file test.md
2. Create a second file §2\ test.md
3. Link the second file in the first file
4. Only the first file will be recognized

How are you linking to it?

For example I have a file called: 202102241246 §1 Zettelkasten.md

In its content I have:

## Objectif

- [[202102081550 L'objectif d'un slip-box]]

which is linking the file 202102081550 L'objectif d'un slip-box.md

The problem is that even neuron query doesn't return any file with a § on it.

Okay. That character is not allowed in the whitelist:

I'm trying to recall the rationale for that. Filesystem filepath and URI limitations are the main reason I think.

Nice, I was wondering where you defined the parsing whitelist. I propose to add this special character to the whitelist (except if there is a way to add personal whitelist in the config file)

Sounds good to me, feel free to open a PR (the CI will catch any errors).
