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.
