See Git - Protocols | Yarn  for details regarding installing from Git.

In Deno with esm.sh:

import { isUnicodeSupported } from 'https://esm.sh/@flex-development/is-unicode-supported'

In browsers with esm.sh:

<script type="module">
  import { isUnicodeSupported } from 'https://esm.sh/@flex-development/is-unicode-supported'
</script>

import isUnicodeSupported from '@flex-development/is-unicode-supported'

console.log(isUnicodeSupported())

This package exports the identifier isUnicodeSupported.

The default export is also isUnicodeSupported.

Check if Unicode is supported.

This can be useful to decide whether to use Unicode characters or fallback ASCII characters.

👉 Note: The function assumes all non-Windows terminals support Unicode and browsers that can correctly render '✓' (U+2713) also support unicode. Windows terminals with unicode support are checked against a hardcoded list.

(boolean) true if unicode is supported, false otherwise

This package is fully typed with TypeScript.
