Bug adding a web page to the Research folder - HTML encoding

When adding a web page to the Research folder, if the URL contains special characters then Scrivener will fail to properly HTML Encode/Decode those characters.

Proper URL: msdn.microsoft.com/en-us/library … =office.15
URL stored by Scrivener: msdn.microsoft.com/en-us/library … ce.15%2529

The failure is in the parenthesis:
0x0028 40 LEFT PARENTHESIS (
0x0029 41 RIGHT PARENTHESIS )
