has-unicode 2.0.1

The npm package "has-unicode" is designed to make a best-effort determination if the terminal being utilized supports unicode. The primary utility it provides is the ability to detect UTF-8 support, as this is what Node itself supports. However, please note that terminals with UTF-16 locales won't be detected as unicode capable by the package.

To actively use the "has-unicode" npm package in JavaScript coding, firstly import it using the require function. For a simple implementation, call the imported function. If unicode support is detected, it returns true; otherwise, it returns false. A more sophisticated implementation involves calling the tryHarder method on the imported function, which takes a callback function as an argument. The callback function gets called with a boolean argument indicating whether or not unicode is supported.

Here are usage examples:

var hasUnicode = require("has-unicode")

if (hasUnicode()) {
  // the terminal probably has unicode support
}

var hasUnicode = require("has-unicode").tryHarder
hasUnicode(function(unicodeSupported) {
  if (unicodeSupported) {
    // the terminal probably has unicode support
  }
})

The documentation for the "has-unicode" npm package is primarily found in its readme file on GitHub, located at git+https://github.com/iarna/has-unicode.git. The readme file provides a detailed outline of what the package does, how it detects unicode support (particularly constraints around UTF-8 detection), and specific considerations for different operating systems. This document should provide all the needed information to effectively integrate and use "has-unicode" in your JavaScript projects.
