Support U+202F / NARROW NO-BREAK SPACE in input strings

[christophflick-toast]

In JavaScript engines that implement unicode ICU 72, Date's toLocaleString function returns a "NARROW NO-BREAK SPACE" (U+202F) unicode character before 'AM/PM'.
Maybe also in other cases, but that's the one where I noticed it.
This leads to an error when used in date-fns parse function.

To reproduce:

1. Go somewhere where date-fns is available in the console, such as https://date-fns.org/v2.29.3/docs/parse
2. Run init() in the console and wait for confirmation
3. Run the following code

const date = new Date()
const localeStr = date.toLocaleTimeString('en-US', {
      hour12: true,
      hour: 'numeric',
      minute: '2-digit'
})
_.parse(localeStr, 'h:mm a', new Date())

You will get Invalid Date.
But if you remove the space or enter a regular space, it's fine.
