Expecting a byte string, but was possibly passed charcters; if the string is actually bytes, please use utf8::downgrade at

Hi RT Team,

Seeking your help on how to configure utf8:: downgrade. As this always encounter an error in RT.

Thank you so much for your help.

Its a warning, not an error. Its coming from the assert_bytes routine in lib/RT/Utils.pm. Unless you have other actual errors after this warning and/or the tickets aren’t being generated correctly, I’d probably ignore it as it just looks like a charset issue.

Does it affect the performance of RT? Because whenever this warning occurs, the performance of RT slows down, so I always restart the server.

Thank you.
