I just want to add my solution  I use german umlauts like            and got the same error   Jarek Zmudzinski just told you how it works  but here is mine   Add this code to the top of your Controller    encoding  UTF-8  for example to use flash message with umlauts   example of my Controller     encoding  UTF-8 class UserController  lt  ApplicationController   Now you can use                     etc

Just a note that as of Ruby 2 0 there is no need to add   encoding  utf-8  UTF-8 is automatically detected

Have you tried adding a magic comment in the script where you use non-ASCII chars  It should go on top of the script      bin env ruby   encoding  utf-8   It worked for me like a charm

User · Answer

Those slanted double quotes are not ASCII characters  The error message is misleading about them being  multi-byte

If you want to add magic comments on all the source files of a project easily  you can use the magic encoding gem  sudo gem install magic encoding   then just call magic encoding in the terminal from the root of your app
