This is to notify you that your issue (logged as “CELLSJAVA-45743”) has been resolved. The fix will be included in our upcoming release (Aspose.Cells v23.12) that we plan to release in the next week. You will be notified when the new version is published.

The xls file is very old Excel 4.0 file ,and there is no code page setting in the file, so we can not select correct encoding.
In the next version, we will get default encoding by region setting:

	LoadOptions options = new LoadOptions();
		options.setRegion(CountryCode.CHINA);
		Workbook wb = new Workbook(dir +"杭职10.31-11.30日明细(2).XLS", options);

It’s better that asking the user resaving the file as Excel 97-2003 or advanced version.

The issues you have found earlier (filed as CELLSJAVA-45743) have been fixed in Aspose.Cells for Java 23.12.
