   @bug 4658679 4879644
   @summary Checks replacement logic within EUC-TW decoder
*/

/*
 * Tests goodness of fix for bugID 4658679: EUC-TW decoder should
 * perform replacement when it encounters latin chars outside the
 * normal US-ASCII range. For example: Isolated occurrences of
 * French accented chars. See bugID: 4658679.
