12302	add_metadata() Fails to Store Serialized Values as BINARY	miqrogroove	ryan	"Symptoms:

WordPress stores corrupt values in post_metadata if there are any non-UTF-8 bytes in the meta_value.

Steps to reproduce:

Call add_metadata() with non-UTF-8 values such as a latin-1 copyright char.

Even though the serialized string goes through prepare() before the query, MySQL is required to truncate the invalid value being assigned to the meta_value field.  The result is that the stored value can never be un-serialized.

This behavior can also be replicated by trying to inject CHAR(169) into any UTF-8 table query."	defect (bug)	new	high	Future Release	Database		critical		needs-patch
