| 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. |
