The best way I'd recommend is to use UTR#50 to determine the orientation
of characters, then split runs by orientation before passing to Harfbuzz.
Unfortunately there's no API to give the data, so you need to get the value
for a character by yourself. There was a request to add to ICU, but it
isn't moving much.
