The most important change is that we now use HarfBuzz by default. Richard didn't contribute the Tai Tham composition rules to us (AFAIR), so I cannot test what happens now in Emacs with HarfBuzz. Maybe we should revisit this issue, but first I hope Richard could tell whether the issue still exists, and if so, what composition rules he uses or suggests to use for Tai Tham.
