The problem that the Ueditor GBK-asp version cannot upload Excel files

The Ueditor 1.4.3.3 and previous gbk-asp versions provided by the official website cannot upload xlsx and xls files, no matter how to modify the config.json configuration file, or comment out the code for checking the file type in Uploader.class.

Solution: I think it is an official vulnerability, and using the UTF-8 version will avoid such problems.
