There is no charset parameter defined for application/json. See https://www.iana.org/assignments/media-types/application/json
The encoding should not be determined by looking at the charset parameter, but rather by looking at the first four octets: https://tools.ietf. org/html/rfc4627#section-3 If you absolutely have to deal with non-conforming parsers, the custom media type is probably the right way to go.
