How can I insert arbitrary binary data into a VARCHAR column?

I have a MySQL table with a VARCHAR(100) column, using the utf8_general_ci collation.

I can see rows where this column contains arbitrary byte sequences (i.e. data that contains invalid UTF8 character sequences), but I can't figure out how to write an UPDATE or INSERT statement that allows this type of data to be entered.

For example, I've tried the following:

UPDATE DataTable SET Data = CAST(BINARY(X'16d7a4fca7442dda3ad93c9a726597e4') AS CHAR(100)) WHERE Id = 1;

But I get the error:

Incorrect string value: 'xFCxA7D-xDA:...' for column 'Data' at row 1

How can I write an INSERT or UPDATE statement that bypasses the destination column's collation, allowing me to insert arbitrary byte sequences?
