| * "Content-Type: text/plain\015\012". Now all the characters in the string |
| * are stored as EBCDIC, only the semantics of \012 is completely |

| * 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. |
