//  gFromTable
//      This is the translation table for IBM037 EBCDIC to Unicode. This
//      table contains 255 entries. The entry for EBCDIC byte x is the
//      Unicode translation of that byte.
//
//  gToTable
//  gToTableSz
//      This is the translation table for Unicode to IBM037 EBCDIC. This one
//      contains a list of records, sorted by the Unicode code point. We do
//      a binary search to find the Unicode point, and that record's other
//      field is the IBM037 code point to translate to.
