Frequently Asked Questions
Unicode escape notation (\uXXXX) is a way to represent Unicode characters using their hexadecimal code point. For example, the heart symbol ♥ is represented as \u2665. This is useful when you need to include special characters in source code that only supports ASCII.
For most cases, escaping only non-ASCII characters (default) is sufficient and keeps your output readable. Escape all characters only when you need maximum compatibility or when working with systems that have strict ASCII-only requirements.
JavaScript, JSON, Python, and Java all use the \uXXXX format for 4-digit hex codes. The main difference is in how they handle special characters and whether they support extended formats. Choose the format that matches your target programming language.
