   @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.
