This issue is involved in three methods, CSV::open, CSV::read and CSV::foreach.

The document of CSV::read says "This method also understands an additional 
:encoding parameter that you can use to specify the Encoding of the data 
in the file to be read. You must provide this unless your data is in 
Encoding::default_external()."
However, when the :encoding parameter is not provided, the encoding of the CSV data 
is treated as ASCII-8BIT. Not as Encoding.default_external.
CSV::open and CSV::foreach are also similar. 

I think the actual behaviour of these methods doesn't conform to the document of these.
