Re: [apps-discuss] [Technical Errata Reported] RFC6839 (4367)

[Yakov Shafranovich <[e-mail]>]

[For context, this is originating from the work at the W3C regarding CSV files]

There appears to be an issue about how to specify encoding
considerations for media types that can be encoded in UTF-8, UTF-16
and UTF-32. For media types, the valid choices are 7-bit, 8-bit and
binary, which would mean that UTF-16 and UTF-32 are binary. For JSON
specifically, since both RFCs define JSON, there is a conflict.

There are two ways to write this then:

1. As in RFC 6839:

"When JSON is written in UTF-8, JSON is 8bit compatible ([RFC2045]).
When JSON is written in UTF-16 or UTF-32, JSON is binary ([RFC2045])."

2. As per RFC 7159:

"binary"

What I am arguing is that the second approach would make more sense.
Just like RFC 7159 choose to use "binary" in case of multiple UTF
encodings, we should follow the same approach in RFC 6839. If not,
then RFC 7159 should have errata pointing back to RFC 6839.

Thanks,
Yakov
