Shape/Reordering characters
The shaping engine inserts a placeholder glyph (U+25CC) wherever
combining marks occur without a valid base. The character U+25CC
belongs to the class of generic bases (GB). Well-formed Javanese
character clusters are defined as follows:
Cases:
Simple non-compounding cluster: < IV | P | D | S | R | WS | O | WJ >
Cluster terminating in Halant: < C | GB > [VS] [N] (H C [VS] [N])* H
Complex cluster: < C | GB > [VS] [N] (H C [VS] [N]) [MCR] [MCY] (VPre) (VAbv) (VBlw) (M)*
