Description

This is kind of related to #9799

With the ICU 72.1 update, it replaces a ascii space character with a narrow non-breaking space unicode character for intl space So something like

(new IntlDateFormatter('en_US', -1, 3))->getPattern();

will return h:mm\u202fa instead of h:mm a.

When creating date strings based off that pattern with the NNBS character, and then passing into strtotime, strtotime returns false.

With the ICU update, I think functions like strtotime should support parsing the NNBS character.

The following code:

<?php
$pattern = (new IntlDateFormatter('en_US', -1, 3))->getPattern();
$timeString = date($pattern, date('now'));
$timestamp = strtotime($timeString);

Resulted in this output:

false

But I expected this output instead:

a unix timestamp
