php Convert Chinese to English?

Problem description:

This is the case, the website does not support it Chinese file names, so when storing files, the Chinese file names must be converted into English format, but when used, the file names in English format must be converted into Chinese, so that we can understand them clearly. (No need to record the file name in the database)

For example, there is a file called "Beauty.jpg". When stored, it is converted into "��Ů.jpg" by urlencode, and then converted by urldecode, so that it can be displayed on the web page. When viewing the file on the Internet (just viewing the file name), "Beauty.jpg" is still displayed.

The urlencode function can convert, but in many cases the file name after conversion is too long, causing the file creation or name change to fail. I don’t know if there are any other functions with similar functions!

Problem Solution:

This class can help you, but rare characters may not be able to achieve it
