PROC HTTP - how do I encode for ÆØÅ

[jmic_nyk]

This code work fine - except for encoding of special characters ÆØÅ (and others). How do I change the encoding to UTF-8?

You don't write what you are encoding from to. But my guess is that the file you are attempting to download is in uft-8 while SAS data is in wlatin. 

If this is the case, the best option is to change the encoding from uft-8 to wlatin. You can do this using filename. 

filename resp "C:\Temp\utf8file.txt" encoding='utf-8';
filename resp1 "C:\Temp\wlatinfile.txt" encoding='wlatin1';

data _null_;
  infile resp;
  file resp1;
  input;
  put _infile_;
run;

Hope it works

First of all it's an upload (a PUT method) - the job is to post a file on a webserver.

Second, I have tried the encoding option with the filename - SAS fails big time. The webserver is UTF-8 (I think). ÆØÅ posted from my program is not ÆØÅ when recieved on the webserver (but something strange). I somehow have to enconde (some of) the request-file as UTF-8 before I PUT it.

I still think it would work in reverse. Take a wlatin file and saving it as an utf-8 file. 

It's a little hard to test, as I can not run the code you posted. Maybe you can make a minimal working example?
