invalid byte sequence in US-ASCII (Ruby 1.9 + rails 2.3.8 + mongodb + mongo_mapper)

My setup is:

linux + Ruby 1.9 + rails 2.3.8 + mongodb + mongo_mapper

I followed http://railscasts.com/episodes/194-mongodb-and-mongomapper, that everything is OK first. I can insert English strings successfully, but when I insert some Chinese strings, it inserted, but can't be displayed.

The web page shows an exception:

invalid byte sequence in US-ASCII

I use mongo command to see the data in mongodb, and it's correct. But I don't know why rails can't display them.

thanks in advance

For me the problem was that I was using an older version of ruby. rvm use 2.0 did the trick.

cd $HOME
vi .bashrc

add locale conf below:

export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LC_CTYPE=en_US.UTF-8

save and run: source ~/.bashrc

Everything is okay~

You may correct this error writing this

export LC_ALL="en_US.UTF-8"

to your ~/.profile, ~/.bash_profile or similar. It works like a charm.

check your locale settings of your OS. You need to set up en_US.UTF-8` locale environment variable otherwise you may face this problem.

If you operating system is Ubuntu then you can check your locale by typing the following command.

sudo locale

and then you can re-configure your locale by typing the following command

sudo locale-gen en_US.UTF-8

It may help you. Thanks.

Please add the following lines in your environment.rb .

Encoding.default_external = Encoding::UTF_8
Encoding.default_internal = Encoding::UTF_8

The problem will be solved.

I had this error with a Rack application.

Adding 

   Encoding.default_external = Encoding::UTF_8

   Encoding.default_internal = Encoding::UTF_8

to config.ru resolved it for me.
