That suspicion was why I was hoping it was a temporary aberration.  When
it is so updated, will it support these sequences? Yes, no or undecided?
The Lao section of Microsoft Typography has not yet been updated.  I've
raised a formal issue at
https://github.com/MicrosoftDocs/typography-issues/issues/238 .

Hi Richard,

This is because the sequences include U+0EBA which was added in Unicode 12.0. 
Edge has not updated for Unicode 12 at this time.

Cheers,

Andrew

Also with the sequence , as in the nominative 
singular ສັນທິຕ຺ຖ຺ິໂກ of ສັນທິຕ຺ຖ຺ິກະ, which transliterates as sandiṭṭhika.  
This last example displays perfectly well on HarfBuzz renderers. 

Richard.

Lao Sign Pali Virama and vowels above

2019-05-20 Thread Richard Wordingham via Unicode
When a consonant bears both U+0EBA LAO SIGN PALI VIRAMA (acting as a
nukta) and a vowel above, is there or is there intended to be any
constraint on there relative order?  While U+0EBA has canonical
combining class 9, the vowels above have canonical combining class 0,
so the order makes a difference.

Typographically, these marks don't interfere, but renderers may
consider that to be a problem. 

The example of nukta and vowel below has now gone up on Wiktionary at
https://en.wiktionary.org/wiki/ວິຍ຺ຍ຺ູ .  The rendering worry arises
with the other form of the instrumental plural masculine.

MS Edge is currently giving me dotted circles for the sequences
 and .  I trust this is just a temporary aberration.

Richard.
