Unicode String Normalizer

A utility that transforms JavaScript code containing unicode escape sequences in string literals to use the actual unicode characters.

Capabilities

Transforms unicode escape sequences

• Given source code with "\u0048\u0065\u006C\u006C\u006F", returns code with "Hello" @test
• Given source code with emoji escapes "\u{1F600}", returns code with the actual emoji character @test
• Given source code without unicode escapes, returns the code unchanged @test

Handles edge cases

• Given invalid JavaScript syntax, throws a parse error @test
