Why didn't the smilies show up on the site?

Question

Debian

There is a WordPress site. Previously hosted on a different hosting. In the headlines, and just in the text, emoticons were used - scissors, balls - in short, the same ones that are on your smartphones.
After moving to a new hosting, instead of emoticons, question marks began to be displayed. Naturally - the coding.
Logged in via SSH. Entered: Selected
$ dpkg-reconfigure locales
and installed ru_RU.UTF8 and ru_RU.CP1251. The first one was made default.
Rebooted the server. Nothing changed.
What could be the problem?
UPD
Moreover, smiles are visible in the URL, but not in the title. Here is a screenshot:

Apparently, this is already in the database with question marks. Why then did emoticons transfer normally for URLs, but not for titles?
