Reconciling Script and Script_Extensions Character Properties

The Unicode Technical Committee would like to eliminate some ambiguity in the assignment of the character properties Script and Script_Extensions and is seeking input from developers.

There are currently a small number of characters whose Script value is explicit (neither Common nor Inherited) and whose Script_Extensions value set has more than one value (a “diverse” value set). These characters are not typical; most characters with a diverse Script_Extensions value set have a Script value of either Common or Inherited. Possible policies and solutions are discussed and outlined in the proposal:
