IsChinaByEmoji library lets browsers detect Chinese users via emoji analysis

The IsChinaByEmoji project provides a TypeScript function to infer Chinese users in a browser. The function examines specific emoji patterns that are more common among users in China. Developers can integrate the code to tailor content based on regional detection. The approach relies on Unicode emoji usage rather than IP or GPS data. The repository is open‑source and includes usage examples. It aims to help sites personalize experiences without invasive tracking. The method may have limitations due to varying emoji preferences. Contributors encourage testing across different browsers to ensure reliability.
