It's my understanding that ZWSP mean breaking oppertunity for word. Ok, How
can I break cluster for the myanmar word. In your example, Myan is one
cluster and mar is one cluster. We really need cluster breaking for burmese
In Last request, I founded some pitfall in Unicode Chapter 10. So, I will
propose some additional case for ZWNJ. Because of either some cluster will
not be ended with ZWNJ or ZWNJ placed Between Virama Sign and tone mark. So,
We hope to add ZWNJ or ZWJ at the end of every cluster in Burmese.

ZWNJ really needed for IDNs and useful for visible virama rendering. Shall
we intend to add end of every cluster?
In Khmer this would be more problematic, as the ZWNJ is mostly used to
