The npm package "is-unicode-supported" is a terminal-check utility. It is used to detect if the terminal environment a program is running in supports Unicode characters. The utility can be a valuable tool in case a developer needs to decide between displaying Unicode or fallback ASCII characters in command-line output. Although the check it performs is quite simplistic, presuming all non-Windows OS support Unicode and having a hardcoded list of Windows terminals that do, the utility reportedly serves its purpose well in popular packages.
To use the "is-unicode-supported" utility, start by installing the package in your project's root directory with the npm install is-unicode-supported command. Upon successful installation, import the package into your JavaScript file. Call its default exported function to determine if the terminal currently supports Unicode. Here is a practical code example:
import isUnicodeSupported from 'is-unicode-supported';
console.log(isUnicodeSupported()); // logs 'true' if Unicode is supported
The call to isUnicodeSupported() returns a boolean value: true will indicate Unicode support, while false will signify the lack of it.
The documentation for the "is-unicode-supported" npm package is embedded in its README file. The README is hosted with the package's source code on the GitHub repository under the URL git+https://github.com/sindresorhus/is-unicode-supported.git. The README file provides guidance on how to install and use the utility, along with a brief introduction to the package's function and relevance.
