Please reach out if you're looking for a Node.js API or CLI engineer (11 years of experience). Most recently I have been Netlify Build's and Netlify Plugins' technical lead for 2.5 years. I am available for full-time remote positions.

Background

While ASCII characters display correctly on all terminals, this is not the case of all characters. When building a terminal application or tool, it is common to experience cross-platform issues like:

The main reasons are:

The terminal font might not include this specific character.
The terminal encoding may not support Unicode. For example, Windows default terminal (Console Host) often use specific encodings like CP437, CP850 or Windows-1252.
The application might not be properly converting encodings when reading or writing terminal characters.

The first two points can be solved by using characters known to display correctly on most terminals and environments. This repository contains a list of those characters:

in this README.md
as a characters.txt file
as a binary printing the full list
as a Node.js module for programmatic usage

Terminals

This was tested on the following terminals, with their default font and encoding.

List of characters

The following characters work on most terminals.

When the character is displayed, its Unicode codepoint is shown above it.

Text file

The list is available in characters.txt. The file is UTF-8 encoded.

CLI

The following command prints the list of characters and their codepoints.

npx cross-platform-terminal-characters

API

A Node module is available to retrieve the list of characters above or detect non-cross-platform characters.

npm install cross-platform-terminal-characters

import {
  regex,
  codepoints,
  characters,
} from 'cross-platform-terminal-characters'

// false, i.e. cross-platform
console.log(regex.test('≈'))
// true, i.e. not cross-platform
console.log(regex.test('≐'))
// Remove not cross-platform characters, i.e. print `example ≈ test  text`
console.log('example ≈ test ≐ text'.replace(regex, ''))

// Array of codepoint integers: [0x0008, 0x0009, ..., 0x25cf]
console.log(codepoints)
// Array of single-character strings: ['\b', '\t', ..., '●']
console.log(characters)

This package works in Node.js >=18.18.0.

This is an ES module. It must be loaded using an import or import() statement, not require(). If TypeScript is used, it must be configured to output ES modules, not CommonJS.
