Summary:
When a URL is copied out of the Adressbar that contains characters disallowed in an URL (unless they are percent-encoded) these characters should be copied percent-encoded, else the resulting URL is invalid, according to RFC 1738

Steps to Reproduce:
1. Visit some URL that contains special characters, for example the Rails UTF-8 checkmark (✓) or umlauts (öäü…) like:
https://www.speakerinnen.org/de/search?utf8=%E2%9C%93&q=test&button=
2. Hit enter to load the page
3. Copy the URL out of the Adressbar


Expected Results:
The URL should be copied percent encoded to be valid:
https://www.speakerinnen.org/de/search?utf8=%E2%9C%93&q=test&button=

Actual Results:
The URL is copied as displayed in the Adressbar, causing it to be invalid since it contains not allowed characters:
https://www.speakerinnen.org/de/search?utf8=✓&q=test&button=

Version:
Safari Version 8.0 (10600.1.25)

Notes:
This wrong behavior doesn't happen when sharing the URL using the Share Button.

Configuration:
MacBook Pro (Retina, 13", End 2013)
OS X Yosemite 10.10 (14A389)
