you should probably not use encode_utf8() on query results

Query results are data coming into Perl, so if anything you would use decode or decode_utf8, but since DBD::mysql version 4, with mysql_enable_utf8, the driver handles this automatically. My use of encode is solely for OUTPUTting the results to the console.

Do not use methods (like encode_utf8()) that convert to utf-8 but don't set the utf-8 flag for this purpose, since if/when this issue in DBD::mysql gets fixed, those methods will not work correctly.

I don't understand what issue you're referring to here. The issue of handling UTF-8 with MySQL has already been fixed, no?

My understanding is that you make sure that Perl understands what your string contains (eg use decode_utf8 to convert input into Perl's internal string format) - this may or may not set the UTF8 flag depending on what characters the string contains. The driver will then handle the conversion to UTF-8 bytes for storage in the database.
