Concise Unicode character names in JavaScript

J. S. Choi, 2022

⚠️ Warning: This article is not finished. The code will not yet run without errors.

All programmers must manipulate text; JavaScript programmers are no exception. Text manipulation often refers to specific characters, usually by their code points in hexadecimal – or by embedding the characters directly in source code.

Did you know you can install fonts without elevation?

The catch is that they're only available for the duration of your session. They are, however, available in all apps across the system.

Someone asked about how to do it on Facebook this week, and at first, I just pointed them at the install script for PowerLineFonts which loops through all the fonts in a folder and install them.

I've used this more than a few times to install some fonts, including the PowerLine ones, which are great:

$sa = New-Object -ComObject Shell.Application

	// Compile with: clang fallback.m -framework CoreGraphics -framework CoreText -framework Foundation -o fallback
	// Run with: ./fallback "Fallback Font Family" "Text to Typeset"

	#import <ApplicationServices/ApplicationServices.h>
	#import <Foundation/Foundation.h>

	int main(int argc, char *argv[])
	{
	if (argc != 3)
	return 0;
