description: >
Case-insensitive Unicode RegExps should not apply full case folding mappings
info: |
Canonicalize ( _rer_, _ch_ )
1. If _rer_.[[Unicode]] is *true* and _rer_.[[IgnoreCase]] is *true*, then
a. If the file `CaseFolding.txt` of the Unicode Character Database provides
a simple or common case folding mapping for _ch_, return the result of
applying that mapping to _ch_.
b. Return _ch_.
See https://unicode.org/Public/UCD/latest/ucd/CaseFolding.txt for the case
folding mappings.
