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

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" -
Kelvin Xiongrorra, did you figure out a work around for this issue?

Sebastian A. EspindolaEveryone 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..
