/* This table is (almost) identical to the previous one. The only difference
* is the fact that it maps every EBCDIC *except 0x0A* to its ASCII
* equivalent. The reason for this table is simple: Throughout the
* server, protocol strings are used in the form
* "Content-Type: text/plain\015\012". Now all the characters in the string
* are stored as EBCDIC, only the semantics of \012 is completely
* different from LF (look it up in the table above). \015 happens to be
* mapped to \015 anyway, so there's no special case for it.
*
* In THIS table, EBCDIC-\012 is mapped to ASCII-\012.
* This table is therefore used wherever an EBCDIC to ASCII conversion is
* needed in the server.
