100 | http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the |

607 | would need different lookups depending on whether PCRE2_UTF was set or not. |
608 | This would make it impossible to use characters in switch/case statements, |
609 | which would reduce performance. For a theoretical use (which nobody has asked |
