WPDB: When sanity checking a string by sending it to MySQL for conversion checks, the incorrect data structure was being returned from wpdb::strip_invalid_text(), causing all write queries to fail for some character sets when the query contained non-ASCII characters.

Merge of [32261] to the 3.9 branch.

See #32051.
