Is there a script tag registry, or is it now a free-for-all as with font
names? (I suppose it is implicitly constrained by what the individual
renderers recognise.)
The nearest to a registry I can find is at
https://docs.microsoft.com/en-us/typography/opentype/spec/ttoreg, but
that appears to be limited to what Microsoft supports - "The tag
registry defines the OpenType Layout tags that Microsoft supports".
None of the Indic 3 script tags are there.
Richard.
