#3538: MailNotifier and UserList appear to get confused with Unicode user names

----------------------+------------------------------
 When a user has non-ASCII characters in his/her name the notification
 email seems to get confused.

 I am obscuring some of the details, but basically the "To" portion of the
 email gets formatted incorrectly, even though the body appears to have the
 correct information. Here is an example the malformed message:

 {{{

 From: <support at foo.com>
 Date: Fri, Apr 22, 2016 at 4:53 PM
 Subject: buildbot failure in blah on blah
 To: Eğre Fo"@foo.com, "o <efoo at foo.com>"@foo.com


 The Buildbot has detected a new failure on builder blah while building.
 Full details are available at:
     blah

 Buildbot URL: http://build.foo.com/

 Buildslave for this Build: blah

 Build Reason: The SingleBranchScheduler scheduler named 'master branch'
 triggered this build
 Build Source Stamp: [branch master] xxx
 Blamelist: Eğre Foo <efoo at foo.com>
 }}}



 Also, when clicking on Buildbot's user list, this particular user (who has
 Unicode characters in his name) is not listed.
