If you think is-number can be replaced with a one-liner, you don't have the enterprise code mindset. What if the world gets more inclusive and MMXXIV, ½ and ⠼⠁ become recognized as numbers? 𒐍𓆾 were numbers in the past but what if people start assigning numeric value to other characters? Are 🖐🔟💯🆢🂵🀌🁅 numbers of the future???

I'm not even all kidding, Regex implementations are split on whether "٣" matches \d.

It's simple ⅯⅯⅩⅩⅣis a number, MMXXIV is not.

You may argue that writiing 2024 as "MMXXIV" and not "ⅯⅯⅩⅩⅣ" is a mistake but while typists who'd use "2OlO" for "2010" (because they grew up using cost-reduced typewriters) are dying out, you'll never get everyone to use the appropriate Unicode for Roman numerals.
