Update info of project with "complex" name fails

[SalticHash]

I started working on a project called Aritmética Espacial and when I try to archive it or add a repository link it fails.

URL on search bar: https://hackatime.hackclub.com/my/project_repo_mappings/Aritm%25C3%25A9tica+Espacial
URL on error: https://hackatime.hackclub.com/my/project_repo_mappings/Aritm%C3%A9tica+Espacial
So the é is getting replaced by %25C3%25A9

Information from ChatGPT

é in UTF-8 = C3 A9
URL encoding turns that into %C3%A9
If that string gets encoded again, the % signs become %25
So it becomes %25C3%25A9

That would mean the string got double encoded somehow?
