21.2.2.8.2 Runtime Semantics: Canonicalize ( ch )
The abstract operation Canonicalize takes a character parameter ch and
performs the following steps:
1. If IgnoreCase is false, return ch.
2. If Unicode is true,
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. Else, return ch.
