Unable to parse http://www.test.com/BMF%20Ver%F6ffentlichungen?

Seems the parse function generate an error for this URL: http://www.test.com/BMF%20Ver%F6ffentlichungen?

Logs:

>>> import hyperlink
>>> hyperlink.parse("http://www.test.com/BMF%20Ver%F6ffentlichungen?")

Hi Damien! Hyperlink by default is reporting that the %F6 in your URL is invalid text when decoded from UTF-8. We can try adding the decoded=False parameter to get a result:

>>> hyperlink.parse('http://www.test.com/BMF%20Ver%F6ffentlichungen', decoded=False)
URL.from_text('http://www.test.com/BMF%20Ver%F6ffentlichungen')

This approach gives you a URL with mostly the same interface as a DecodedURL (the default output of parse), but be aware that you may run into issues when trying to treat parts of that URL as text vs bytes. Hope this helps!

@mahmoud thanks, we are investigating if we can use the decoded flag.
