MySQL: Why does the MAX(varbin) function return hieroglyphs?

Question

MySQL

If in MySQL a value of type varbinary is passed to the aggregate function MAX(), then the result of the function is a string in the form of hieroglyphs, i.e. query:
select max(0x258770100075258F)
will return the following:
But I did not find any restrictions on the type of the argument value in the documentation. What could be causing this, any ideas?

Answer 1

MAX([DISTINCT] expr)
Returns the maximum value of expr. MAX() may take a string argument; in such cases, it returns the maximum string value

Answer 2

This is your value 0x258770100075258F as a UTF-8 string
