Frequently asked questions
What is Unicode encoding used for?▼
Unicode escape sequences are commonly used in JSON, JavaScript source code, and configuration files to safely represent non-ASCII characters like Chinese, Arabic, or emoji.
Does it support emoji?▼
Yes. Emoji and all Unicode characters are correctly handled, including those above U+FFFF that require surrogate pairs.
What's the difference from UTF-8 encoding?▼
Unicode encoding uses \u escape format (common in source code and JSON). UTF-8 is a byte-level encoding used in network transmission and file storage.
