How can I set Mail.app back to being the default mailto: protocol handler?

I tried unsetting the mailto: protocol in chrome://settings/handlers, but the only result is that now mailto: links don't open at all.  (They still switch focus to Chrome.)

According to this answer, the file that needs to be edited is ~/Library/Preferences/com.apple.LaunchServices.plist.  However, checking the file contents with the file command shows that it is a binary file:
