Re: Khmer orthographic reform

Here's a small doc with a timeline and some sources:

I think my proposal would be the subtag "-kmpre20c", indicating a
spelling of Khmer predating the reforms of the 20th century. Looking
at the timeline I can't really find a better name... Would that be a
reasonable request or are there some red flags?

Best,
