Re: POST Request with non-null-terminated string

thanks for the answer, I got a few more suggesting the same option. I tried it today and it worked fine. I have a follow up question though. In the string I'm sending there are extended ASCII characters. I'm currently sending them to a test server and what I'm getting back is incorrect. However since I haven't set up the server it's hard for me to know if the problem is with curl or with the way the server is set up, so I wanted to know if the extended ASCII chars in the POST field are getting sent correctly. I tried searching but I only found suggestions to URL encode them, which in my case is impossible, since the server is supposed to read the HEX value of the symbol using the Latin 1 encoding.

Best Regards,
