Yes, it does avoid the problem:
if (!$sql_allow_8bit_address) { s/[^\040-\176]/?/g for @$keys_ref }
...
my($datatype) = $sql_allow_8bit_address ? SQL_VARBINARY : SQL_VARCHAR;
The $sql_allow_8bit_address controls the data type used in an argument
of a query, and if false, it also turns 8-bit characters into '?'.

The chosen $datatype (as above) affects a type of arguments resulting
from %k and %a placeholders in a query (SQL lookups), as well as a
data type of an email address in table maddr (SQL logging, aka PenPals).

I'm not sure. There is always a choice of using an SQL conversion function
on expressions in a query, or type casting.
