What URL escaping does GitHub markdown expect?

Question

I have a markdown file checked into GitHub, and in this file I want to link to the following URL:

https://query.wikidata.org/#%23 Diplomatic missions with no operator.%0ASELECT DISTINCT%0A%09%3Fwikidata%0A%09(SAMPLE(%3Ftype_label) as %3Ftype)%0A%09(SAMPLE(%3Fcountry_label) as %3Fcountry)%09%0AWHERE {%0A%09{ %3Fwikidata p%3AP31%2Fps%3AP31%2Fwdt%3AP279* wd%3AQ3917681. } UNION { %3Fwikidata p%3AP31%2Fps%3AP31%2Fwdt%3AP279* wd%3AQ7843791. } %23 Embassy or consulate%0A%09%3Fwikidata p%3AP31%2Fps%3AP31 %3FtypeId. %3FtypeId wdt%3AP279* wd%3AQ43229. %3FtypeId rdfs%3Alabel %3Ftype_label.

Unfortunately, GitHub fails to understand the link, the link appears as text.
I tried replacing all spaces with %20, it does not work either:

How to escape the URL so that GitHub markdown correctly creates the link?

Answer 1

You'll need to encode your parentheses in order for GitHub to correctly parse the link. You can see this by typing the bare URL into the GitHub editor. GitHub will underline a natively-typed link, but in yours it only underlines up to the first open parentheses:

Replacing your open parentheses ( with %28 and your close parentheses ) with %29 will allow GitHub to correctly process the link. The updated URL would be:
