# Data updated to OpenType 1.8.2 as of January 2018.

# Complete list of OpenType script tags at:
# https://www.microsoft.com/typography/otspec/scripttags.htm

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