Is it possible to enter character codes in a SQL query to insert into a table?

Question

PHP

Is it possible to enter character codes in a SQL query to be inserted into a table so that they are interpreted by the database as characters, that is, is it possible to escape characters by writing their code, for example \0x10? Of course, you can implement the storage of character codes in the form of text with interpretation on the client side, but you yourself understand all the disadvantages.
