      It's possible to insert non valid utf-8 encoded strings into a collection. The driver needs to check after #force_encoding that the encoding is indeed valid.

      For example: 

      1.9.3-p545 :006 > string = "\xED\xAE\xBA\xED\xB6\x86"
 => "\xED\xAE\xBA\xED\xB6\x86" 
1.9.3-p545 :007 > string.encoding
 => #<Encoding:UTF-8> 
1.9.3-p545 :008 > string.valid_encoding?
 => false 
1.9.3-p545 :009 > coll.insert({"not-valid" => string})
 => BSON::ObjectId('5399da013005c8cf8a000001') 
1.9.3-p545 :016 > coll.find().to_a.first["not-valid"].valid_encoding?
 => false
