# is-unicode-supported > Detect whether the terminal supports Unicode This can be useful to decide whether to use Unicode characters or fallback ASCII characters in command-line output. Note that the check is quite naive. It just assumes all non-Windows terminals support Unicode and hard-codes which Windows terminals that do support Unicode. However, I have been using this logic in some popular packages for years without problems. ## Install ``` $ npm install is-unicode-supported ``` ## Usage ```js const isUnicodeSupported = require('is-unicode-supported'); isUnicodeSupported(); //=> true ``` ## API ### isUnicodeSupported() Returns a `boolean` for whether the terminal supports Unicode. ## Related - [is-interactive](https://github.com/sindresorhus/is-interactive) - Check if stdout or stderr is interactive - [supports-color](https://github.com/chalk/supports-color) - Detect whether a terminal supports color - [figures](https://github.com/sindresorhus/figures) - Unicode symbols with Windows fallbacks - [log-symbols](https://github.com/sindresorhus/log-symbols) - Colored symbols for various log levels
