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