Reviewing IETF documents

[Florian Weimer]

Is someone constantly reviewing IETF documents (drafts and RFCs) which
use UTF-8 or other Unicode-related technology?

It seems that some WGs have not much experience in Unicode issues
and just permit UTF-8 in places were formerly only ASCII was
allowed, and are not fully aware of the consequences (multiple UTF-8
representations of the same glyph, additional control characters, to
name just two).
