/**
 * Used by CLDR tooling; not in ICU4C.
 * Note, this will not work correctly with normal skeletons, since fields
 * that should be related in the two skeletons being compared - like EEE and
 * ccc, or y and U - will not be sorted in the same relative place as each
 * other when iterating over both TreeSets being compare, using TreeSet's
 * "natural" code point ordering (this could be addressed by initializing
 * the TreeSet with a comparator that compares fields first by their index
 * from getCanonicalIndex()). However if comparing canonical skeletons from
 * getCanonicalSkeletonAllowingDuplicates it will be OK regardless, since
 * in these skeletons all fields are normalized to the canonical pattern
 * char for those fields - M or L to M, E or c to E, y or U to y, etc. -
 * so corresponding fields will sort in the same way for both TreeMaps.
 * @deprecated This API is ICU internal only.
 * @hide original deprecated declaration
 * @hide draft / provisional / internal are hidden on Android
