Is "сом" identical to "com"? (the first of these is U+0441U+043E U+043C)

I've heard it argued repeatedly that this is an unreasonablerule for ideographic characters. I don't have an opinion, buthope that ICANN has considered that case in full details.

This rule would permit such TLDs as "1F" or "0F", which I'm notpersuaded are good ideas given what some operating systems (asdiscussed on this list) think might be "digits".
I also trust that ICANN has obtained an agreement from ISO,signed in some appropriate medium like blood, that the ISO3166-1 alpha-2 code list will not be expanded to includeletter-digit combinations when the 50-year rule (new with ISO3166-1:2007) causes them to run short of codes.

This is, IMO, much too subtle and admits of cases that willconfuse some applications. It is not an accident that thestatement in 1123 can (and, if my recollection of 1591 iscorrect, should) be interpreted as prohibiting TLDs that arenon-alphabetic. That rule obviously needs to be modified forIDN A-labels, but should still be treated with care, IMO.

See above.

As a rhetorical question relating to several of the othercomments in this thread, has the IETF been formally asked toreview and sign off on these rules?
