Sanitize img description with Umlaute

[eutervogel]

Hi, 

I've build a little Page for my brother where he can upload a cvs file to upload multiple images at a time. The images contain a german desc an english desc numer of likes and so on.
Everything is working fine so far, but when the german description contains ä, ö or ü the description field stays emtpy. 

I tried too use different sanitizers, but, no luck so far. 

$string = 'Drosselrohrsänger';

$string = $sanitizer->entities($string);

echo $string

No output 

What am I doing wrong?

Are your PHP script and the CSV file both in UTF8?

The PHP file is. Csv needs to be checked. I'm afk at the moment but thanks for the tip. 

 

Edit: The problem was, that the CSV was not in UTF-8.

 

Thanks!
