BufferClusterLevel

enum BufferClusterLevel : Enum<BufferClusterLevel>

Data type for holding HarfBuzz's clustering behavior options. The cluster level dictates one aspect of how HarfBuzz will treat non-base characters during shaping.

In @HB_BUFFER_CLUSTER_LEVEL_MONOTONE_GRAPHEMES, non-base characters are merged into the cluster of the base character that precedes them.

In @HB_BUFFER_CLUSTER_LEVEL_MONOTONE_CHARACTERS, non-base characters are initially assigned their own cluster values, which are not merged into preceding base clusters. This allows HarfBuzz to perform additional operations like reorder sequences of adjacent marks.
