Re: [ddlm-group] [THREAD 4] UTF8

Hi Herbert and others: perhaps predictably, I disagree with this
proposal.  Herbert, I think we need to get some thoughts from the rest
of the group, but for what it's worth I've inserted my (predictable)
comments below.

Disagree: there should be no requirement to include a UTF8 identifier,
as that is the only encoding in the scheme I am proposing.

OK, insofar as people are free to add functionality to their software
anyway; but a file in an alternative encoding is not to be considered
a valid CIF, so frankly I hope that there is no perceived need for the
ability to handle other encodings.

As I don't think we should support use of non UTF-8 encodings,
obviously I don't endorse us making any recommendations along these
