All URLs containing non-ASCII characters are considered invalid

[goulvench]

The current URL validation relies on URI.parse, from the standard library, which only works with ASCII.
The following valid URLs are therefore rejected: 'http://example.com/caractère-accentué', 'http://ουτοπία.δπθ.gr'.
The Addressable gem correctly parses these URLs, and could be used as a drop-in replacement instead.
Would you be interested in a PR?
