I'm writing a WebAPI which required to handle HTTP POST and the body will include Chinese characters and emoji. I wrote a loop back test but I found that the WebAPI returns "?" when I use cURL to test. Is there any example or best practice on how to handle those kind of characters?
a!localVariables( local!json: if( isnull(http!request.body), a!fromJson("{""hello"":""world 中文 😀""}"), a!fromJson(http!request.body) ), a!httpResponse( headers: { a!httpHeader(name: "Content-Type", value: "application/json") }, body: a!toJson(local!json) ) )
% curl --location \ --request POST 'https://my.server.com/suite/webapi/LoopBack' \ --header 'Content-Type: application/json;charset=utf-8' \ --header 'Authorization: Bearer abc.def.ghi' \ --data-raw '{"hello":"world 中文 😀"}' {"hello":"world ?? ?"}%

Hi Daniel, I hope this might be useful for you to understand some context over
This occurs when the Web API does not send an appropriate "Content-Type" header with a character set included, which the client system relies on to interpret the content sent by the Web API.
Content-Type"
And I would suggest to Explicitly specify the Content-Type header with the relevant character set in the SAIL code for the Web API using a!httpHeader in the headers parameter of the a!httpResponse
Content-Type
a!httpHeader
a!httpResponse
For example, to correctly send JSON with the UTF-8-character set.
headers: { a!httpHeader( name: "Content-Type", value: "application/json; charset=utf-8" ) }
