Property ScriptFallbackFonts
ScriptFallbackFonts
Gets or sets the per-script glyph-level fallback chains. When a resolved font is available but lacks a glyph for a specific codepoint, the shaper resolves that cluster against the chain keyed by the codepoint's UnicodeScript — distinct from family-level substitution, which handles a missing font. Empty by default.
