Ruby on Rails - Generated Files' Encoding

I have discovered that all the files RoR generates when creating a new application seem to be saved with Western(ISO-8859-1) encoding (I am developing locally on a Windows machine). As a result I am having problems when using certain special characters eg £.

• Should 开发者_StackOverflow社区RoR be generating the framework files and saving them with Western(ISO-8859-1) encoding?
• If not, how can I get RoR to generate the files and save them with UTF-8 encoding, and so avoid problems with certain characters eg £?

Please see Ruby on Rails - £ sign troubles for a previous unresolved question I asked relating to this problem.

Rails only uses ASCII characters in generated files.

ASCII files are neither UTF-8 nor ISO-8859-1. ASCII is compatible with both encodings, but an ASCII file doesn't become an ISO-8859-1 or UTF-8 file until you add a special character to it.

When you save a file after adding a £ character, you should make sure to set up your editor or IDE to use UTF-8 instead of ISO-8859-1. You should look for a configuration option in your editor. Rails cannot do anything about it.

If you run Ruby 1.9, also remember to set a magic comment at the top of a file containing special characters (except in templates). In Ruby 1.8 and previous versions, this comment has no effect.

# encoding: utf-8

The exact same problem causes the symptoms you describe in your other question.
