Error displaying person contacts

Bug report

Title

Error in displaying contacts of persons if you save the contact title with the characters “i”, “ї” and other characters of the Ukrainian alphabet

Issue Description

Since we work in Ukraine, our clients may have the symbol “i”, “ї” and other letters of the Ukrainian alphabet in their names.
When I filled in the “/admin/contacts/persons” section with clients without using the Ukrainian alphabet, everything was fine.
But when I added a client using the Ukrainian alphabet, I started getting the error “malformed utf-8 characters possibly incorrectly encoded”.
It is important to fill in the contact through the administrative panel; if you add the characters through the database, there is no problem.

Preconditions

• MariaDB 10.5 (utf8mb4, utf8mb4_unicode_ci)
• PHP 8.2

Steps to reproduce

1. Go to /admin/contacts/persons/create and create a contact using the Ukrainian alphabet.
2. After that, on the /admin/contacts/persons/ page, I start getting the error “malformed utf-8 characters possibly incorrectly encoded”.

Actual result

Current status:
