| Support for surrogate pairs within patterns match by the CharacterClass Atom |
| info: | |
| The production Atom :: CharacterClass evaluates as follows: |
| |
| 1. Evaluate CharacterClass to obtain a CharSet A and a Boolean invert. |
| 2. Call CharacterSetMatcher(A, invert) and return its Matcher result. |
| |
| Runtime Semantics: CharacterSetMatcher Abstract Operation |
| |
| 1. Return an internal Matcher closure that takes two arguments, a State x and |
| a Continuation c, and performs the following steps when evaluated: |
| [...] |
| d. Let cc be Canonicalize(ch). |
| [...] |
