\cx meaning
[quote]
(When PCRE is compiled in EBCDIC mode, all byte values are valid. A lower case letter is converted to upper case, and then the 0xc0 bits are flipped.)

I am not sure I understand these words "and then the 0xc0 bits are flipped"! Please explain to me (and perhaps modify the documentation next time), if we have, let's say, the letter 'A' which is \xC1 in EBCDIC, what would happen with the pattern /\cA/ ?
