662    character constants like '*' because the compiler would emit their EBCDIC code,
663    which is different from their ASCII/UTF-8 code. Instead we define macros for
664    the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
665    is enabled. When UTF-8 support is not enabled, the definitions use character
666    literals. Both character and string versions of each character are needed, and
667    there are some longer strings as well.
668    
669    This means that, on EBCDIC platforms, the PCRE library can handle either
670    EBCDIC, or UTF-8, but not both. To support both in the same compiled library
671    would need different lookups depending on whether PCRE_UTF8 was set or not.
672    This would make it impossible to use characters in switch/case statements,
673    which would reduce performance. For a theoretical use (which nobody has asked
674    for) in a minority area (EBCDIC platforms), this is not sensible. Any
675    application that did need both could compile two versions of the library, using
676    macros to give the functions distinct names. */
