+/* Ideas:
+   - Generalize run length encoding + index for all tables
+   - remove redundant tables for ID_start, ID_continue, Case_Ignorable, Cased
+
+   Case conversion:
+   - use a single entry for consecutive U/LF runs
+   - allow EXT runs of length > 1
+
+   Decomposition:
+   - Greek lower case (+1f10/1f10) ?
+   - allow holes in B runs
+   - suppress more upper / lower case redundancy
