My goal
I’d like to have a short presentation and a topic to discuss.
Bopomofo Layout with OpenType font feature.
Five years ago, I attended the i18n workshop in Keio Univ. to place a presentation for the status and requirement of Bopomofo layout.
Now it's nearly done. The last step is to use OpenType feature for arranging tone mark's position. Recently we published a test font file and it worked on Firefox and Google Chrome (see Bopomofo on the Web).
It’s a good case from i18n requirement and thorough HTML5 standard (the ruby markup), to CSS (ruby-position) and font (OpenType GPOS ‘vert’ feature). Finally back to asking browsers' support.
This workshop focus on advance layout, but also a good chance for me to finalize the Bopomofo issue.
Discuss Mixed layout EPUB display fragmentation.
EPUB 3 standard allows to insert pre-paginated asset in a reflow book. It's an important feature for authors to make digital publications in great layout. But it's not widely supported by all reading systems.
If we can fill the gap between reading systems, it will be great help to improve current digital publication's presentation.
