Wenlin Variation Sequences depend on Wenlin CDL font support: Wenlin uses a whole plane of Private-Use Area (PUA) characters (U+F0000..U+FFFFD), to define its own Private-Use Variation Selectors (PVS). Wenlin uses these PVS to define Wenlin’s own Private Variation Sequences, used to manage glyph variation in the CDL Database.
