Murata-san has been directly involved in the process of authoring the SC34
liaison, I’d like to delegate it to him to provide us with the summary.


Since ISO/IEC directives do not allow me to disclose the liaison statement
here, let me give a summary as well as some historical background from the
SC34's point of view.

Fonts are in the scope of SC34
<https://en.wikipedia.org/wiki/ISO/IEC_JTC_1/SC_34#Scope>.  But SC29
started standardization of OFF anyway and claimed OFF is in its then scope
<https://en.wikipedia.org/wiki/ISO/IEC_JTC_1/SC_29>.  SC34 has spoken with
SC29 (on and off) without much success.

In its recent liaison statement to SC29, SC 34 has offered to collaborate
with SC 29 in a Joint Working Group.  SC 34’s offer was discussed by SC
29/WG 11, which at the time was responsible for OFF (but has been disbanded
recently).  SC 29/WG 11 decided that SC34 did not provide sufficient
justification to start a revision project, so recommended to SC 29 not
to start a revision project and not to form a Joint Working Group with SC
34 to handle the revision.  While OFF remains the responsibility of SC 29
within JTC 1, there is nothing that SC 34 can do to revise OFF.

Since SC34 has document format standards (OOXML, ODF, and EPUB), SC34 cares
about interactions of fonts and document processing.   SC34 feels that
interactions between fonts and document rendering applications have not
been clearly defined.  In our understanding, different applications
interact with fonts in different ways and this leads to divergent behavior.
However, users expect that modern applications connected by the Internet
exhibit behavior that is predictable and consistent. In particular, users
expect that different web browsers on different platforms provide
reasonably similar results when rendering documents.

SC34 is very interested in collaborating with any experts who share our
views about the limitations of OFF.
