### Description This is kind of related to #9799 With the [ICU 72.1 update](https://icu.unicode.org/download/72), it replaces a ascii space character with a narrow non-breaking space unicode character for intl space So something like ```php (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 <?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 ``` ### PHP Version 8.2.8 ### Operating System Redhat Enterprise 8.8
