Can't Handle a Request That Contains Non-ASCII Character (Emoji)

[rafazzaky]

So I'm having this problem where my api-gateway (that use go-micro) can't handle a request that contain an emoji. The error message that I receive is \"id\":\"go.micro.client\",\"code\":500,\"detail\":\"header key \\\"request\\\" contains value with non-printable ASCII characters\" I was wondering is this go-micro related or something else? I hope I can find an answer in this discussion. My current solution is to encode the request and then decode it in my api-gateway.

I've never seen an emoji in a http header. Is that the case?

No, the case is that I use an emoji on the request body but somehow it identified as a header, for example, when I send this request

{
    "message":"this is a message"
}

it will work, but somehow when I send this request

{
    "message":"this is a message with emoji🙏"
}

it wont work and responded with an error "contains value with non-printable ASCII characters"
