By default HSSF uses cell values and sheet names as compressed unicode, - so to support localization you should use Unicode. - To do it you should set it manually:

- - // for sheet name - HSSFWorkbook wb = new HSSFWorkbook(); - HSSFSheet s = wb.createSheet(); - wb.setSheetName( 0, "SomeUnicodeName", HSSFWorkbook.ENCODING_UTF_16 ); - - // for cell value - HSSFRow r = s.createRow( 0 ); - HSSFCell c = r.createCell( (short)0 ); - c.setCellType( HSSFCell.CELL_TYPE_STRING ); - c.setEncoding( HSSFCell.ENCODING_UTF_16 ); - c.setCellValue( "\u0422\u0435\u0441\u0442\u043E\u0432\u0430\u044F" ); -
