Default charset for CSV files #44

Closed JeniT closed 9 years ago

JeniT commented 9 years ago

RFC4180 defines the default charset as US-ASCII because that was (at the time RFC4180 was written) the default charset for all text/* media types. This has been superseded with RFC6657. Section 3 of RFC6657 states "new subtypes of the "text" media type should not define a default "charset" value. If there is a strong reason to do so despite this advice, they should use the "UTF-8" [RFC3629] charset as the default."

Do we have a strong reason to specify a default charset? Should IETF be defining application/csv instead, to avoid doing unrecommended things with a text/* media type.

For the existing "text/csv" type, I plan to publish a new RFC amending the media type to do just that. For "non-text" MIME types, in the application tree, this is not an issue.

UPDATE: Actually scratch that - the current IANA registration already does that based on RFC 7111

For completeness, here is the reference to Yakov's mail sent to the mailing list.

Thanks, I've removed the issue from the syntax document.

One more thing - while the default character set has changed, I don't believe the ABNF grammar has been updated
