+# 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
+```
+

+
+Returns a `boolean` for whether the terminal supports Unicode.
