Using the text "text UTF-8 text" creates a link automatically in Confluence on the "UTF-8" part of the text

Steps to reproduce:

1. Get an OnDemand instance that has JIRA as well, on fireball 185-187.
2. On A confluence page write any sentence that contains "UTF-8", and the UTF-8 part of the text will become a link as "https://<instancename>.atlassian.net/browse/UTF-8.

EDIT: Just found out that this also effect ISO formatted dates like " 2012-11-15" it will return an invalid JIRA link.

Edit2: This appears to affect also strings like "rxx", "r3543", where it produces a link that looks lik "https://<instance name>/source/changelog/TP/?cs=343"
