5
6# Most of the script tags are the same as the ISO 15924 tag but lowercased,
7# so we only have to handle the exceptional cases:
8# - KATAKANA and HIRAGANA both map to 'kana';
9# - spaces at the end are preserved, unlike ISO 15924;
10# - we map special script codes for Inherited, Common and Unknown to DFLT.
