1034    the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
1035    is enabled. When UTF-8 support is not enabled, the definitions use character
1036    literals. Both character and string versions of each character are needed, and

1039    This means that, on EBCDIC platforms, the PCRE library can handle either
1040    EBCDIC, or UTF-8, but not both. To support both in the same compiled library
1041    would need different lookups depending on whether PCRE_UTF8 was set or not.
1042    This would make it impossible to use characters in switch/case statements,
1043    which would reduce performance. For a theoretical use (which nobody has asked
1044    for) in a minority area (EBCDIC platforms), this is not sensible. Any
