How to Remove Question Marks in Diamonds in WordPress?

Question

Character encoding

Hello, I have a WordPress site. Everything works on the news pages, but on the main page, the news is cut off and sometimes the last character is replaced by a question mark in a rhombus.

This template uses text cropping by ancient methods.
You need to find in the template where the output of this text is or the trim function itself by the number of characters and replace at least with mb_strimwidth if you really need to trim by the number of characters.
