The Myanmar font builds were okay at 3.2-3231. But from 3.2-3232, the mkmk feature is not working as expected.
Test: ငှ့ ငု့
Problem: the dotbelow does not attach to all of the below marks.
mkmk produced in 3231:
mkmk produced in 3234, a difference here is the use of UseMarkFilteringSet:

Thanks Sovichet! I was Zooming with Georg about this in October. The problem is the lookupflag. It needs to restrict the context using UseMarkFilteringSet @belowmarks. Without the lookupflag, as in the first example, any abovemark in between the two belowmarks will break the mkmk attachment. The second example looks like the lookup is restricted to just the dotbelow glyph, so the rules trying to attach it to other belowmarks won’t have any effect.

i wonder if anyone can respond. We haven’t been able to export any Burmese fonts correctly for a month and need this to be fixed please
Can you call me to show what is not working?
Yep, I can Skype tomorrow. Currently none of the mkmk is working at all, as far as I can tell. The lookupflag UseMarkFilteringSet is incorrect
This is fixed in version 3241.
I know we thought we’d fixed everything after a Skype a few months ago, but there’s something fishy going on here. The sequence here is ယႂႍ ယႂꧥႍ and the tonemark 108D comes last in the sequence but anchors on the left of any other belowmark. When there’s no abovemark in the sequence it works fine (left cluster) but when there’s a vowel above, the mkmk anchoring isn’t working (right cluster). (It’s attaching instead to the bottomleft anchor of the consonant ယ.)
Maybe we just fixed it for ‘bottom’ and ‘bottomright’ anchors, but in this case we’re concerned with the ‘bottomleft’ anchor?
I don’t know Burmese, but based on the characters in your post here and in the input field in the screenshot, it doesn’t look like it works right in the left cluster either – should the tone mark not be combined with the right-half-circle (ṵ vowel?) rather than being under the left half of the consonant?
The left cluster is correct with the tonemark anchored to the left of the belowmark.
Can you send me a sample font?
