In an off-list discussion with Khaled Hosny regarding a specific case of shaping text with Harfbuzz, he suggested setting cluster levels to a certain value to improve handling of values returned by Harfbuzz.
I can see that the code has three possible values for cluster levels: * HB_BUFFER_CLUSTER_LEVEL_MONOTONE_GRAPHEMES = 0 * HB_BUFFER_CLUSTER_LEVEL_MONOTONE_CHARACTERS = 1 * HB_BUFFER_CLUSTER_LEVEL_CHARACTERS = 2 I looked at the docs, and there doesn’t seem to be any kind of explanation. So my question is: 1. What exactly are cluster levels? 2. What do the above values mean?
