There is a problem when the encoding is not set correct on a Server
I made tests with a simple php file:
<?php
echo "Hällo Wörld"
?>
A HTTPRequest gives me
> Hällo Wörld
<?php
header("content-type: text/plain; charset=utf-8");
echo "Hällo Wörld";
?>
Here the response is correct
> Hällo Wörld
It seems that when no encoding is set, UTF-8 is not used as default. That's a problem for some translater APIs for example. I don't know if it is possible to set utf-8 as fallback encoding or if a change could produce other issues.
Maybe take a look on it
