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.

npm install is-unicode-supported

import isUnicodeSupported from 'is-unicode-supported';

isUnicodeSupported();
//=> true

Returns a boolean for whether the terminal supports Unicode.

• is-interactive - Check if stdout or stderr is interactive
• supports-color - Detect whether a terminal supports color
• figures - Unicode symbols with Windows fallbacks
• log-symbols - Colored symbols for various log levels
