This would be my favourite lettering medium, except someone keeps stealing my stylus and chewing on it.

I recently came across this great photograph of my father teaching at Leeds College of Art in the late 1950s. Coincidentally, I was dressed very similarly.

In my @atypi presentation about the Skeena Indigenous project, I spoke about how we shouldn’t presume non-literate societies lacked ways to record and transmit information.

Today, I came across this Diné (Navajo) cantillation aide-mémoire, painted on muslin cloth for easy transport. The prayer sticks illustrated along the bottom indicate the sequence of chants and their repetition.

Following a link from @moyogo led me to this proposal from 1911 to replace all the writing systems of India with a new ‘Imperial Script’. The accompanying article now seems almost quaint in its assertions and rhetorical devices.

Apparently I am going to be speaking backwards at @atypi from 16:30 to 16:00 on the Saturday. That feels about right at this point, as I am still waiting confirmation that I can use some of the indigenous language samples in my slides, and maybe the permission will arrive by the time I reach the beginning of the talk at the end of the session.🤪

Apple Core Text (in Pages) is spacing the sequence correctly, idicating a different methodology in run segmentation.

The bug seems to be specific to U+1DBF (raised theta): other raised modifier letters are kerned correctly.

Horrible thought: this may be because U+1DBF was assigned the script=Greek property (even though it is a character that only occurs in the context of Latin-based alphabets!—don’t get me started).

Confirmed ☹️ — this is a run segmentation issue resulting from the raised theta being classed as Greek.

Thanks @khaled for pointingout how to diagnose this in FontGoggles and test without segmentation.

Now off to test in other environments...

Cross-script kerning · Issue #808 · googlefonts/ufo2ft

Since #679, kerning pairs are split per-script, under the assumption that OpenType layout is not applied across scripts. As it turns out, there are more than one implementation that applies at leas...
