funny, I was looking into this yesterday!
I am by no means an expert, but I think that what it is happening is the
following:
application/json implies UTF-8: if you look at the MediaType class from
akka http you se the declaration:
val `application/json` = awfc("json", HttpCharsets.`UTF-8`, "json")
second, get the data from your service with curl/wget and have a look.
When I did in my experiment the data in the file was correctly rendered as
UTF-8.
now, why non-ascii characters are messed up when you look at it in the
browser? I think that the browser is trying to render json as HTML, and
since the data is not html it defaults to HTML default encoding, which is
ISO-8859-1 (https://www.w3schools.com/html/html_charset.asp), so it renders
your data incorrectly.
In conclusion I believe that is not akka http at fault, but the default
behavior of all web browser (I saw it on chrome and safari): your data is
fine, it is just displayed wrongly when you look at it in a browser
