Will a path to content such as
example.com/content type/page name work? or must it have a filler such as dashes -
Spaces should be at least encoded as %20 .
It's not a good practice, not a standard, to use spaces in URLs at all. In my opinion it is better to replace all spaces with dashes or to concatenate them.
Spaces will cause problems with links, for example you might get:
- www.example.com/problem with link
