That might backfire, not all code points are characters, and not all abstract characters can be encoded by a single code point. The glossary in TUS 5.0 offers: | Code point: Any value in [...] the range of integers from 0 | to 10FFFF [hex.]. [BOM] > It might be worth adding a note something along these lines: "The > BOM is useful in establishing the endian-ness of UTF-16 and UTF-32 > encodings, but serves no useful purpose in the context of UTF-8." It's an important "signature" for plain text files on platforms where UTF-8 is not the local codepage. One of these platforms is quite popular. :-) For the purpose of the net-utf8 I-D just saying NO to BOMs is IMO good enough, RFC 3629 contains the fine print. > I'd ruthlessly whack about 80% of the history and suchlike > explication. Oops, no, the history is essential to understand old telnet issues like IAC without reading pre-historic RFCs with numbers below 821. > Future consumers of this document, of which I predict there will > be many, will need to consult and then cite the meat I think the future consumers are standard developers and protocol designers trying to update say RFC 3912. Appendix C lists future work, indirectly that defines the main audience for net-utf8. Frank
