BidiProperties

BidiProperties :: # (opaque)

Scalar mappings and binary facts used by UAX #9, sourced from UnicodeData.txt, BidiMirroring.txt, and BidiBrackets.txt. These queries expose Unicode character data; they do not perform paragraph analysis, mirroring, or visual reordering.

mirroring_glyph : Scalar -> [Some(Scalar), None]

Return the optional character-based best-fit mirror mapping. Absence is meaningful even when is_mirrored is true.

paired_bracket : Scalar -> [Some(PairedBracket), None]

Return the optional reciprocal bracket mapping and open/close type.
