The charset parameter is not defined for the application/json media type according to RFC 8259. JSON is defined to be UTF-8 by default, and adding this parameter is redundant and technically non-compliant with the specification.

To further optimize the payload size and serialization performance, consider setting ensure_ascii=False in json.dumps. This prevents the escaping of non-ASCII characters into \\uXXXX sequences, which is particularly beneficial if the data contains any non-ASCII text and aligns with the explicit UTF-8 encoding being introduced.

Suggested change
self.wfile.write(json.dumps(data, separators=(',', ':')).encode('utf-8'))
self.wfile.write(json.dumps(data, separators=(',', ':'), ensure_ascii=False).encode('utf-8'))
