Is that the case for ISO-2022-JP encoders as well? If so, a note to that effect should probably be added to the specification. Otherwise, the algorithm needs to be modified. 78223 1 VYV03354 2012-11-12 15:36:16 +0000 ISO-2022-JP doesn't contain JIS X 0212 from the start. (But ISO-2022-JP-1 and ISO-2022-JP-2 do.) 78232 2 pub-w3 2012-11-12 20:18:33 +0000 Indeed, I was using the term ‘ISO-2022-JP’ improperly to refer to a series of related encodings including JIS (the predecessor of ISO-2022-JP), ISO-2022-JP, ISO-2022-JP-1, ISO-2022-JP-2, ISO-2022-JP-3 and ISO-2022-JP-2004, as well as hybrids and variants. The issue I was trying to raise is that the encoder does not mirror the decoder, and that this asymmetry is not mentioned. 78250 3 pub-w3 2012-11-12 23:31:30 +0000 As you were probably alluding to, the various versions are not necessarily handled identically. Safari and Opera both distinguish between at least two variants: If the MIME charset is ISO-2022-JP-2, JIS X 0212 is decoded and encoded. For ISO-2022-JP, on the other hand, JIS X 0212 characters are encoded as deciamal character references, and Safari does not decode JIS X 0212 data either. 78264 4 VYV03354 2012-11-13 12:21:01 +0000 I don't see the point of differentiating ISO-2022-JP variants. We already treat some ISO encodings as just aliases of Windows encodings. Regarding the asymmetry, I agree to add some explanations. 78327 5 pub-w3 2012-11-14 23:05:00 +0000 It looks like I misinterpreted your comment twice. Sorry about that. I think we are in agreement. Given that IE has never supported JIS X 0212 (not sure about recent versions), it probably makes sense to use it only for the decoder. Only a note acknowledging the asymmetry is missing. 78405 6 annevk 2012-11-16 12:50:17 +0000 https://github.com/whatwg/encoding/commit/04d78180f9dc07f471ae432cebe34915c03412de
