Unicode Support
All three platforms support patterns that contain Unicode multibyte characters (see Table 8 - 12 ). On
Neko, the regex support is provided by the PCRE library that must be compiled with the Unicode
support; the Windows setup, starting from haXe version 1.16, adopts the Unicode support by default.
Table 8-11
Syntax Description
(?=expr) Positive look-ahead. The pattern must be followed by a second pattern
defined in expr but expr is not included in the match.
(?!expr) Negative look-ahead. The pattern must not be followed by the
sequences that match expr.
(?<=expr) Positive look-behind. The pattern must follow a string that matches
expr. JavaScript does not support look-behinds.
