As currently defined, the encoding is specified through a flag (see http://w3c.github.io/csvw/syntax/#dfn-encoding) and must be one of the values specified in the encoding spec. It is either set explicitly in the JSON metadata document supplied for the CSV file or through the charset in the Content-Type header. Otherwise it defaults to utf-8.

Would you recommend an alternative approach?

What would you recommend that we say? The comments from Steven on behalf of the I18N WG simply said “not in Unicode”, would that be a better way of framing it than “not a Unicode encoding”?

Are you asking us to list the encodings that aren’t Unicode encodings, in the spec?

Please suggest improved wording where it’s not right; you’re the experts. We’re also very happy to receive pull requests.
