Subject: pgsql: Support Unicode full case mapping and conversion.
Date: Fri, 17 Jan 2025 23:59:48 +0000
Message-ID: <E1tYwFg-0029Dj-L5@gemulon.postgresql.org> (raw)
Support Unicode full case mapping and conversion.
Generate tables from Unicode SpecialCasing.txt to support more
sophisticated case mapping behavior:
* support case mappings to multiple codepoints, such as "ß"
uppercasing to "SS"
* support conditional case mappings, such as the "final sigma"
* support titlecase variants, such as "dž" uppercasing to "DŽ" but
titlecasing to "Dž"
