Escape encryption / UnEscape decryption

Escape is an encoding method that converts non ASCII characters in a string (such as Chinese, Japanese, Korean, etc.) into ASCII code, allowing these characters to display normally in URLs or HTML. UnEscape is the reverse operation of Escape, which can decode and restore the encoded string of Escape to the original string. Through Escape and UnEscape operations, we can safely transfer various types of data during network transmission.
