is-unicode-supported
Advanced tools
The is-unicode-supported npm package is a simple utility that allows you to check if the environment where your Node.js application is running supports Unicode. This can be particularly useful when you want to ensure that Unicode characters are displayed correctly in the terminal or console.
Check Unicode support
This feature allows you to check if Unicode is supported in the current environment. The function returns a boolean value indicating the support status.
const isUnicodeSupported = require('is-unicode-supported');
if (isUnicodeSupported()) {
console.log('Unicode is supported!');
} else {
console.log('Unicode is not supported.');
}The supports-color package is used to detect whether a terminal supports color. While it does not directly check for Unicode support, it is similar in the sense that it checks for terminal capabilities.
The has-unicode package is another utility that checks if the process's stdout stream is connected to a terminal that can display Unicode. It is similar to is-unicode-supported but may have different implementation details or checks.
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.
