How to deal with question mark in Magento?

Question

Magento

In the database, utf8_general_ci is everywhere.
Template file in utf8 format.
Where else can you look?

Answer 1

I can’t say specifically about magento, but you clearly have substr by utf string there. Replace with mb_substr.

Answer 2

It is best to cut to a space, and as they said above, this is all because of the multibyte encoding.

$text = "Текст который надо обрезать до пробела, очень большой текст бла бла бла";
$text = preg_replace("/^(.{30}[^\,\s]*[\,\s])(.+)$/ui","\\1",$text) ;
echo $text;
