php preg_replace iOS apostrophe

Question

How do I replace the iOS apostrophe ’ with php using preg_replace ?

I tried

preg_replace("/(\u2019)/", '-', $mytring); //Compilation failed: PCRE does not support \L, \l, \N{name}, \U, or \u

preg_replace("/(’)/", '-', $mytring); //Not working

Based on answer, I tried

preg_replace("/(\x{2019})/u", '-', 'it’s'); //it’s

But I'm on Windows, does it matter?

Edit: OK it works now, I had to html_entity_decode it first and I couldn't see it from the dump. Thanks to people who answered.

*Not working* isn't helpful at all. Please provide a live demo. With PCRE it is `\x{XXXX}` not `\uXXXX`. — revo, Aug 21 '18 at 15:32
Warning: preg_replace(): Compilation failed: character value in \x{} or \o{} is too large — Eric, Aug 21 '18 at 15:35

You should be able to do it with this:

$result = preg_replace('/\x{2019}/u',"-", $mytring);

You can catch Unicode using \x{xx} and use the /u modifier (PCRE_UTF8) when you need a character value length of 4:

preg_replace('/\x{2019}/u', "'", $mytring);

@Eric I'm on Windows too, and your edit shows the same regex as before, is it normal ? – AymDev Aug 21 '18 at 15:50
please refresh... also what version of PHP are you using? – Eric Aug 21 '18 at 15:51
@Eric yes you used the `/u` modifier but did not catch unicode using `\x{2019}`. PHP 7.2.1. – AymDev Aug 21 '18 at 15:54
