False positive on link with url encoded character

[MihaiDamian]

I have the following snippet in one of my html files:

<link rel="prefetch" href="data/c%23.csv">

On disk, the linked file is named c#.csv so I am url encoding the number sign character in html.

html-proofer reports the following error when encountering this:

index.html: internally linking to data/c%23.csv, which does not exist

This can't be right. I'm referencing a few more files from the same path and this is the only one that produces an error, so the issue is definitely related to the encoded character.

The same is true for basic (utf-8) characters. Believe it's a limitation in URI.parse.
