From liam at fromoldbooks.org Thu Feb 6 04:02:43 2025 From: liam at fromoldbooks.org (Liam R. E.

In testing, people building actual fonts found this overflowed and needed to be 24 bits, so we have a proposed change, Change dataOffset from Offset16 to Offset24. My understanding is that this has already been implemented in harfbuzz, since its an ISO draft and since it was necessary... No other problems were found so far. The PDF file enclosed says the same thing, using the ISO template for comments (numbered as if made sa a US comment; the Canadian mirror committee meeting is tomorrow) liam -- Liam Quin,?https://www.delightfulcomputing.com/ Available for XML/Document/Information Architecture/XSLT/ XSL/XQuery/Web/Text Processing/A11Y training, work & consulting.

Note that HarfBuzz support is, of course, disabled by default, and not delivered in the wild. -------------- next part -------------- An HTML attachment was scrubbed... URL:
