欧洲'é'字符，ASCII码为101 204 129

Question

I have an issue with the character 'é'.

With a ftp_nlist($this->ftpStream, $directory); I've a string like that 'Parté.mp4' but the 'é' doesnt match the regex [\p{L}]*\.mp4

There are example here:

• The one who work : http://regex101.com/r/yH9xG0/1

• The one who doesn't: http://regex101.com/r/bI4lN2/2

The ASCII code of the 'é' who doesn't work is '101 204 129'. The function ord($e); where $e is the weird character return '101' which is the code of the simple letter e.

It's seems like my 'é' is composed of three characters because I've to make a
$e = substr($fileName,4,3); to obtain my single character.

I would like to be able to authorize these characters in my regex... If you have any leads, thanks.

Use the extended unicode option.

\X*.mp4

Regex Demo

Here's the PHP manual that describes the extended unicode option.

The \X escape matches a Unicode extended grapheme cluster. An extended grapheme cluster is one or more Unicode characters that combine to form a single glyph. In effect, this can be thought of as the Unicode equivalent of . as it will match one composed character, regardless of how many individual characters are actually used to render it.
