Re: [ddlm-group] Community consulation regarding CIF2 encoding

Dear Colleagues,

   Unless we are assuming that the CIF2 transition is not acutally
going to happen, that transition is going to involve a wide range
of both software developers and users of crystallographic software
throughout the community.  Either we have te dicsussion with them
on a UTF-8-ony standard now, or we will have to have the discussion
with them later, when it is much harder and more expensive to
revise what we will have done.

   If James is reluctant to post his own summary to the lists, then
how about the following:

   COMCIFS, the IUCr Committee of the Maintenance of the CIF standard
is considering some important improvements and extensions to CIF.
Among the extensions being considered is enlarging the character
set allowed from simple ASCII to the full UNICODE character set
(the same set of characters used in web browsers with HTML and 
in XML).  There is strong disagreement on COMCIFS as to whether
this would best be done by mandating just a single UNICODE encoding,
UTF-8, or whether is would be best to follow the practives of HTML
and XML in allowing alternate encodings.  The full thread of the
discussion thus far can be seen at:


Comments from interested members of the community would be
