I would take the opposite view. If the address is a valid email address  
according to RFC 2822, then it SHOULD be possible to create a mailto URI  
for it. It some stupid person chooses a complicated email address with  
strange characters in it, and wants to publicise it on some website. then  
he will just have to put up with the ugliness of the URI - he has only  
himself to blame, especially if he creates it wrong. The vast majority of  
people do not choose such awkward names.

But if you forbid %-encoding, then over-officious software is going to  
reject perfectly good URIs unnecessarily whilst at the same time more  
liberal software will happily handle them. Getting the over-officious  
sites to change their ways if youm later decide to allow them will be  

And it is not as if disentangling %-encoding is hard. Every site handling  
URIs already contains the code to do it.
