Module: Fontisan::Cldr::IndexBuilder

Defined in:
lib/fontisan/cldr/index_builder.rb

Overview

Builds the per-language codepoint index from a cached CLDR JSON archive and persists it as a YAML file for future Index loads.

Walks every main/<lang>/characters.json file under the cached archive, extracts exemplarCharacters (plus auxiliary and index sets when present), parses each via UnicodeSetParser, and unions the result into a single codepoint set per language.
