 * A transliterator named Any-T or Any-T/V, where T is the target
 * script and V is the optional variant, that uses multiple
 * transliterators, all going to T or T/V, all with script sources.
 * The target must be a script.  It partitions text into runs of the
 * same script, and then based on the script of each run,
 * transliterates from that script to the given target or
 * target/variant.  Adjacent COMMON or INHERITED script characters are
 * included in each run.
