## problem

H1. Mojo::RabbitMQ::Client does not handle unicode input correctly
https://github.com/inway/mojo-rabbitmq-client/commit/c043447d4fa53a1456515c4def1c4d1367cd87b0#commitcomment-20829251
H2. `lib/OpenQA/WebAPI/Plugin/AMQP.pm` does not forward unicode correctly to Mojo::RabbitMQ::Client

## workaround
only type ascii within comments.
