Mongodb match accented characters as underlying character

Question

In MongoDB "db.foo.find()" syntax, how can I tell it to match all letters and their accented versions?

For example, if I have a list of names in my database:
João
François
Jesús

How would I allow a search for the strings "Joao", "Francois", or "Jesus" to match the given name?
I am hoping that I don't have to do a search like this every time:
db.names.find({name : /Fr[aã...][nñ][cç][all accented o characters][all accented i characters]s/ })

As of Mongo 3.2, you can use $text and set $diacriticSensitive to false:

{
  $text:
    {
      $search: <string>,
      $language: <string>,
      $caseSensitive: <boolean>,
      $diacriticSensitive: <boolean>
    }
}
