[TYPO3-core] RFC: #3527: Bug: Wrongly encoded characters in mail form validation popup

[Francois Suter]

This is an SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=3527

Branches:
4.2 and trunk

Problem:
When a problem happens in the mail form a JS alert box pops up. If the 
field names contain non-latin-1 characters they are badly interpreted.

Solution:
Call decodeURI() on the field name (to balance the rawurlencode() call 
in tslib_content).

Notes:
It didn't seem necessary to call decodeURI() in any other cases. 
decodeURI() is available for IE since v5.5, this seems good enough for me.

I have tested the patch on FF3, Safari 3 and Opera 9. It would be good 
if someone could test it on IE.

Also it would be good if someone working in a non-latin language could 
give it a try too.

Cheers
