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
const isUnicodeSupported = require('is-unicode-supported');
isUnicodeSupported();
//=> true
API
isUnicodeSupported()
Returns a boolean
for whether the terminal supports Unicode.
