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

Answer 1

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.
