FYI: Practical uses of OpenType fontes as another higher level protocol

[Joao S. O. Bueno]

Hi -

Just got this news yesterday which I believe might be of interest for
some of the participants on this list -
People had successfully made use of mechanisms in OpenType fonts
to be able to colorize text according to context. The practical use
is for simple syntax highlighting.

https://blog.glyphdrawing.club/font-with-built-in-syntax-highlighting/?utm_source=tldrnewsletter

This is a protocol sitting between unicode and markup languages,
at the cost of having to be properly configured in any displaying app -
(however, any app using proper libraries for rendering the fonts, and
enabling font selection and parametrization would work "out of the box")


This can also work as one more item to list in the "proper ways to do it
in higher protocols"  when
people involved or interested in Unicode are queried about
 including mechanisms such as enabling color attributes.

Regards,
