As a french user I receive some mails with accented chars in the sender's alias; also, I receive, as anybody, spams from countries that don't use the common characters sets (China, Japan, Russia, etc.). And I can't add these adresses to friends or blocked senders because of the «invalid characters» filter. I saw that some users asked for an unicode support, but there is another way: no need to «understand» (recognize) the extended characters to handle these adresses, I think that there is no reason to consider these characters as «invalid».
For example, there is a sender that appears as «NewsLetter Libération» in my mail software and as «NewsLetter Libération» through Spamihilator. As it seems to me, «Ã©» are «valid characters» as long as the sender's name «NewsLetter Libération» appears each time in the same form, and this is.
I suggest to allow « strange » characters in the sender's alias.
