Knowing that Unicode is composed of plain ASCII characters,
you may perform a conversion test using PHP "recode" function.
You may test each record as follows:
$test = recode ("latin1..u8", $record);
If the $test value differs from the $record one, then it is a Latin1 string.
On the converse, it is Unicode UT-8. There is no garantee. Make a test on a
few values, I am not coding right now and only have access to email.
