Bug #4603
Updated by naruse (Yui NARUSE) almost 12 years ago
=begin 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. =end
