181 ** `translate-region' has been improved in several ways. Its TABLE
182 argument used to be a 256-character string. In addition to this, it
183 can now also be a vector or a char-table (which is useful for Mule.)
184 If TABLE a vector or a generic char-table, you can map characters to
185 strings instead of to other characters. For instance:
186
187 (let ((table (make-char-table 'generic)))
188 (put-char-table ?a "the letter a" table)
189 (put-char-table ?b "" table)
190 (put-char-table ?c ?\n table)
191 (translate-region (point-min) (point-max) table))
