PHP PDO: charset, set names?
...e it in your connection string like:
"mysql:host=$host;dbname=$db;charset=utf8"

Without use utf8 Perl interprets your string as a sequence of single byte characters. There are four bytes in your string as you can see from this:
$ perl -E 'say join ":", map { ord } split //, "鸡\n";'

Data Storage:
Specify the utf8mb4 character set on all tables and text columns in your database. This makes MySQL physically store and retrieve values encoded natively in UTF-8. Note that MySQL will implicitly use utf8mb4 encoding if a utf8mb4_* col...

UTF8 is multi-bytes, and key length is calculated in this way - 500 * 3 * 6 = 9000 bytes.
But note, next query works!
