incompatible character encodings: UTF-8 and ASCII-8BIT (Encoding::CompatibilityError)

[scriptfans]

If the payload message contains Chinese characters, the program will throw an exception:

incompatible character encodings: UTF-8 and ASCII-8BIT (Encoding::CompatibilityError)

How to fix it? thanks.

The current encoding used for the payload of the publish packet is 'ASCII-8BIT'. I would try to add other encoding support. Could you add the full error log? It would help me a lot for debugging
