Convert Unicode to a String Literal helps you escape every character in your text into a Unicode literal format like \uXXXX or surrogate pairs for emoji and symbols. It’s great for creating escaped strings in JavaScript, Java, or JSON, where Unicode literals are required. Whether you’re debugging, preparing input for code, or exporting raw string literals, this tool does the heavy lifting live, with file support and instant preview.
