Subject: Encoding of Emoji in SMS, and UCS-2 vs UTF-16

The SMS standard specifies UCS-2 encoding:

I see many “emoji” have been defined in Unicode 6. But many emoji are outside the BMP, so can’t be encoded in UCS-2. Does anyone know, is the intention that these emoji should be encoded in SMS using UTF-16 rather than UCS-2? Are there any plans in-progress to update the SMS standards to specify UTF-16 rather than UCS-2?

Perhaps this question could be added to the Emoji FAQ. http://unicode.org/faq/emoji_dingbats.html

I haven’t heard from anyone regarding this. Should I ask on some GSM or other mobile standards mailing list instead?

I do think it would be worth adding to the Unicode Emoji FAQ though.
