  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.
