What is Unicode unescaping?

Unicode unescaping is the process of converting escape sequences in the form \uXXXX (where XXXX is a hexadecimal code point) back to the actual Unicode characters they represent. This is useful when working with text that contains escaped Unicode sequences and you want to see the actual characters.

Examples of Unicode unescaping

Unicode escaping in different programming languages

Language	Unicode escape format	Example
JavaScript	\uXXXX	var text = "Caf\u00e9"; // Café
Java	\uXXXX	String text = "Caf\u00e9"; // Café
C#	\uXXXX	string text = "Caf\u00e9"; // Café
Python	\uXXXX or \UXXXXXXXX	text = "Caf\u00e9" # Café
Ruby	\uXXXX	text = "Caf\u00e9" # Café

Note:

This tool only handles the \uXXXX format of Unicode escapes. Some programming languages and systems may use different formats (like \U00XXXXXX in Python for code points above U+FFFF). Make sure your input uses the \uXXXX format for proper conversion.
