Description

Since #4058, the links are no longer encoded.
But the URLs(files name) of the existing pages or new pages are still encoded.

The original link is
https://try.gitea.io/yasuokav/link-test/wiki/Test%3F
but now is
https://try.gitea.io/yasuokav/link-test/wiki/Test?

I couldn't reproduce on the try.gitea.io link but maybe I didn't understand the bug.

@sapk When you click "Click Me" it will lead you to https://try.gitea.io/yasuokav/link-test/wiki/_pages
instead of
https://try.gitea.io/yasuokav/link-test/wiki/Test%3F

Because the URL is no longer encoded as /yasuokav/link-test/wiki/Test%3F

<a href="/yasuokav/link-test/wiki/Test?" rel="nofollow">Click Me</a>

I see, but that logical the file is name : Test%3F
I would see it more like a bug fixed by #4058
In your markdown, [Click Me](Test?) should be [Click Me](Test%3F)

If I take github as a reference :
[Click Me](Test?) -> Click Me
[Click Me](Test%3F) -> Click Me

But we should notice it at the release that it could break some links.

@sapk Yes, you're right. But it will break some links if I use

[[Test?]]

Only [[Test%3F]] will work, but it looks bad.

Maybe we shouldn't encode the file name.

[sapk]

We need to encode the filename (in url) are those char are specials. But in case of [[Test?]] maybe url-encode the reference (link) to the page but not the title displayed.

[sapk]

I would just be encode link here before URLJoin but I will have to test this before PR.
