609    character constants like '*' because the compiler would emit their EBCDIC code,
610    which is different from their ASCII/UTF-8 code. Instead we define macros for
611    the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
612    is enabled. When UTF-8 support is not enabled, the definitions use character
613    literals. Both character and string versions of each character are needed, and
614    there are some longer strings as well.
615    
616    This means that, on EBCDIC platforms, the PCRE library can handle either
617    EBCDIC, or UTF-8, but not both. To support both in the same compiled library
618    would need different lookups depending on whether PCRE_UTF8 was set or not.
619    This would make it impossible to use characters in switch/case statements,
620    which would reduce performance. For a theoretical use (which nobody has asked
621    for) in a minority area (EBCDIC platforms), this is not sensible. Any
622    application that did need both could compile two versions of the library, using
623    macros to give the functions distinct names. */
