UNICODE_SCRIPT_TO_OPENTYPE_TAG_MAPback to summary
private static final Map<String, String[]> UNICODE_SCRIPT_TO_OPENTYPE_TAG_MAP

A map associating Unicode scripts with one or more OpenType script tags. Script tags are not necessarily the same as Unicode scripts. A single Unicode script may correspond to multiple tags, especially when there has been a revision to the latter (e.g. Bengali -> [bng2, beng]). When there are multiple tags, they are ordered from newest to oldest.
