Details:

Steps to reproduce:
1. On a web-server, create an html file with the contents:

<a href="space-ok%20cyrillic-not%D0%B3.txt">target-with-other-char</a>

2. Download that file recursively: `wget -r
http://example.com/wget-test.html`

On Linux, we get the expected (truncated) result:

...
2021-03-25 02:01:59 (4.51 MB/s) - ‘example.com/wget-test.html’ saved [71]

--2021-03-25 02:01:59--  http://example.com/space-ok%20cyrillic-not%D0%B3.txt
...

However on Windows, the urlencoded utf8 character is mangled and fails to
download.

...
2021-03-25 02:02:29 (4.51 MB/s) - ‘example.com/wget-test.html’ saved [71]

--2021-03-25 02:02:29-- 
http://example.com/space-ok%20cyrillic-not%C3%90%C2%B3.txt
...

Note that the space (%20) is not mangled.
