its their database collation. it isnt using a multibyte character set collation.
they will need to update their database to utf8mb4, to support those multibyte character sets you are attempting to use.
there is a conversion tool added in 774 to make this process easier to perform.
or they can instead perform it manually by researching the directions online.
search, "convert iso-8859-1 to utf8mb4 character set collation"
the manual process is complex and can be extremely time consuming with a large database.
