75    PCRE can be compiled to run in an environment that uses EBCDIC as its character
76    code rather than ASCII or Unicode (typically a mainframe system). In the
77    sections below, character code values are ASCII or Unicode; in an EBCDIC
78    environment these characters may have different code values, and there are no
79    code points greater than 255.
