I'm using rails Version 3.0.3 and ruby Version 1.9.2p136 (2010-12-15) on Windows Vista. Script console gives me the following error:

What do you have in 'script/rails'? – Nerian
Did you try executing rails console? That is how to launch the console in Rails3 (i.e. you no longer use script commands). – David Sulc
Yes the command I used is "rails console". – user331471

The problem is that Ruby1.9.2 has some issues with encoding... You have to check if your db driver is not giving error.. Does your server run? I recommend you to use Ruby187

I got the same problem. I spent hours trying to fix it, rebuilding ruby, etc... For any setting of LANG= it was failing.

Finally I discovered in the code that it was during the load of the init file, that is, ~/.inputrc.

My $HOME in the problematic computer had not the ~/.inputrc... I tried to create an empty one and... worked!

So try touch ~/.inputrc

I've just encountered this same issue with rails 4.1.1, and it turned out that my ~/.inputrc file was encoded using the ISO-8859-1 encoding. After converting the file to UTF-8, everything worked fine:

$ iconv --from-code=ISO-8859-1 --to-code=UTF-8 ~/.inputrc >out
$ mv out ~/.inputrc

To check what encoding your inputrc file is encoded with, use:

$ file --mime-encoding ~/.inputrc
