61: * Tables used for conversions to/from IBM and EBCDIC to support an extension
62: * to POSIX P1003.2/D11. The tables referencing POSIX contain data extracted
63: * from tables 4-3 and 4-4 in P1003.2/Draft 11. The historic tables were
64: * constructed by running against a file with all possible byte values.
