I think emoji are killing my WordPress site… How can I debug?

This is a limitation of MySQL’s UTF-8 implementation: it supports just a limited set of valid UTF-8 characters. You can convert your database to utf8mb4, and emojis will work. But there may be other side effects.

See ticket #21212 for details.
