Subject: Re: Encoding::primary_encoding

I made some tests with UFT-8, option "-Ku", option "-Ka" and both types of magic 
coding comments on Windows (Ruby 1.9 built using MSYS). Results are:

1) Both types of magic comments ("# vi: set fileencoding=utf-8" and "# -*- 
coding: utf-8 -*- " on first line) are possible and will be recognized. Both 
overwrite a "-Ka" option and will work if the file doesn't contain a BOM.

1) An UTF-8 file without a BOM will be recognized as ASCII-8BIT and processed 
like this. If the Option "-Ku" ist used, it will be recognised and processed as 
UTF-8 encoded.

Thats all upto now.

Are there other possible values for magic comments? - I didn't find anything in 
the sources.
