[TYPO3] sr_feuser_register: URL encoding in email

[Daniel Calderini]

Hello,

I am using sr_feuser_register with the option enableEmailConfirmation 
activated. The email is sent as plaintext.

The problem is, the URL sent to activate the account is not encoded.
So on certain email applications (like in thunderbird) the address is 
cut after the first bracket.
(If you copy/paste it, it works; but if you click on it, it doesn't.)

Is there a (simple) way to encode the address so it is not be cut?

Best regards
Daniel Calderini
