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