I'm still having some mental block regarding text encoding.

I'm trying to provide non-English data in my API response, in this case Spanish.
Here's a sample part description ("Manómetro") in the Browse window (this table is queried by my API) looking as it should...

I have a test PRG that fetches the JSON from my API using wwHTTP, saves it to a file using StrToFile() and then displays it using MODIFY FILE. A snip of the result is below looking as expected.

But when I execute the same request using Postman, the "ó" character is replaced with a question mark and I don't know where the problem is.

I'm not terribly familiar with Postman and I've looked for a setting in Postman that looks like it might cause this but with no success.
Does anyone know what I'm missing or doing wrong?

Thanks,
Carl

The data returned has to be UTF-8 encoded. Postman fails because it can't render the special character because it's expecting UTF-8.

Make sure the API result is UTF-8 encoded. If you're using the Web Connection REST process it should do that automatically. If you're manually sending your JSON back make sure the serialized data is UTF-8 encoded (there are options on the serializer) and that the response is UTF-8 encoded (by default in Web Connection if you have a reasonably recent version).

Most HTTP clients will automatically decode UTF-8 so it's kind of difficult to see the raw data that's going over the wire. The server sending the data should encode that special character into a two-character UTF-8 code.

You can look at the raw data with wwHttp by making sure to turn off UTF-8 decoding using:

oHttp.lDecodeUtf8 = .F.   && .T. by default

The string that comes back here should not have your accented character in it but the UTF-8 multi-character representation.

If it comes back with your accented character, then the content is not UTF-8 encoded and you need to make sure the request gets encoded on the server.

Thanks for the explanation, Rick.
I have a better understanding of it now.
