| /* If PCRE is to support UTF-8 on EBCDIC platforms, we cannot use normal |
| character constants like '*' because the compiler would emit their EBCDIC code, |
| which is different from their ASCII/UTF-8 code. Instead we define macros for |
| the characters so that they always use the ASCII/UTF-8 code when UTF-8 support |
| is enabled. When UTF-8 support is not enabled, the definitions use character |
| literals. Both character and string versions of each character are needed, and |
| there are some longer strings as well. |
| |
| This means that, on EBCDIC platforms, the PCRE library can handle either |
| EBCDIC, or UTF-8, but not both. To support both in the same compiled library |
| would need different lookups depending on whether PCRE2_UTF was set or not. |
| This would make it impossible to use characters in switch/case statements, |
| which would reduce performance. For a theoretical use (which nobody has asked |
| for) in a minority area (EBCDIC platforms), this is not sensible. Any |
| application that did need both could compile two versions of the library, using |
| macros to give the functions distinct names. */ |
