  I had the same problem with mysql and a utf-8 database

  ruby-1.9.2-rc2 > p = Project.create(:name => 'áéíóú')
   => #<Project id: 2, name: "áéíóú", title: nil, description: nil, start_on: nil, end_on: nil, created_at: "2010-07-27 20:41:06", updated_at: "2010-07-27 20:41:06"> 
  ruby-1.9.2-rc2 > p.to_json
   => "{\"project\":{\"created_at\":\"2010-07-27T20:41:06Z\",\"description\":null,\"end_on\":null,\"id\":2,\"name\":\"\\u00e1\\u00e9\\u00ed\\u00f3\\u00fa\",\"start_on\":null,\"title\":null,\"updated_at\":\"2010-07-27T20:41:06Z\"}}" 
  ruby-1.9.2-rc2 > Project.first.to_json
   => "{\"project\":{\"created_at\":\"2010-07-27T20:41:06Z\",\"description\":null,\"end_on\":null,\"id\":2,\"name\":\"\\ufffd\\ufffd\\ufffd\\ufffd\\ufffd\\ufffd\\ufffd\\ufffd\\ufffd\\ufffd\",\"start_on\":null,\"title\":null,\"updated_at\":\"2010-07-27T20:41:06Z\"}}"

  Now that I check better, my problem was not with the to_json method, but rather with mysql :P

  Being p the record before being saved, and q the record after saving

  ruby-1.9.2-rc2 > p.name
   => "á" 
  ruby-1.9.2-rc2 > q.name
   => "\xC3\xA1"

  Everyone running on Ruby 1.9.x and using MySQL, should use the mysql2 gem.
  It forces the use of UTF-8 and converts to/from UTF-8 automatically when needed.

  • Tag changed from “3.0.0.rc, encoding, to_json” to “3.0, 3.0.0.rc, encoding, to_json”

  Switching to the mysql2 gem doesn't completely solve the problem.

  For example:

  "".to_json.encoding #<Encoding:UTF-8> [].to_json.encoding #<Encoding:US-ASCII>

  Attached is a patch which fixes the issue.

  Alex,
  If I have older versions for ruby and for rails, I have to update both, install the mysql2 gem and update the database data?

  The path you are talking about ... i font understand :(

  Tnk.

  I had the same problem with rendering response as json. I'm uploading images to the database, while rendering it as json

  Eg: render :json => material.to_json

  I'm getting following error

  ArgumentError in ApiController#download_object

  redundant UTF-8 sequence

  But the same thing is working fine with to_xml. Please any one let me know what is the issue here.

  Thanks..
