Defined in:

Overview

Parses ‘Scripts.txt` — the primary Script property assignment per codepoint range.

Format (UAX #44):

XXXX..XXXX ; Script_Name # trailing comment
XXXX       ; Script_Name # trailing comment

Yields one Script per line, with ‘range_first` and `range_last` set. The Coordinator bsearches the resulting sorted array by cp. The ISO 15924 `code` is resolved later by the Coordinator via PropertyValueAliases (property=sc).
