Is there a list of (all, non-custom) URL schemes?
I thought that I just needed to search on google to find tons of answers, but it's probably wrong my (naive) question.
If so, I will settle the (usual) most important:
file://, ftp://, http://, https://, mailto:, news:, telnet://
https://www.iana.org/assignments/uri-schemes (XML, XHTML, CSV, plain text)
It lists all registered (per RFC 7595) URI schemes.
