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

1npm install is-unicode-supported

Usage

1import isUnicodeSupported from "@so1ve/is-unicode-supported";
2
3isUnicodeSupported();
4// => true

API

isUnicodeSupported()

Returns a boolean for whether the terminal supports Unicode.
