Insert Link Containing Single Quote or Curly Braces Doesn't Work

Steps to reproduce:

1. Create a page
2. Edit the page and insert a link e.g. http://localhost/asdsadsad/asdsadsa'asdsad'asdsad
3. Linking does not work when the link contains single quote or curly braces

As referred here: http://www.ietf.org/rfc/rfc1738.txt

Usually a URL has the same interpretation when an octet is
represented by a character and when it encoded. However, this is not
true for reserved characters: encoding a character reserved for a
particular scheme may change the semantics of a URL.

Thus, only alphanumerics, the special characters "$-_.+!*'(),", and
reserved characters used for their reserved purposes may be used
unencoded within a URL.

Workaround 1

URL-encode single quotes to %27 manually

Workaround 2

Using Insert > Web Link in the editor dialog (which will encode the characters for you upon insert)

Workaround 3

Use a TinyURL. Normally Tiny URLs don't have quote or any other special characters. Hence, you can use them instead of full link. If your current links are referring to other Confluence's page you can use Confluence Tiny URL from Confluence Page Information.
