hi, 

I'm trying to understand how to solve a problem i'm having, I hope someone with more experience can enlighten me. 

I'm developing a small app wich does some api call via WinHttp.WinHttpRequest.5.1 . I'm having trouble with a particular get request: the result i get shows some strange characters instead of accented characters. However when I use Fidler to do the seme get request (headers and everyhing are exactly identical) the result i get is correct. the response  I get on Fidler has the characters in the correct way in raw, in text view and all the other tabs except for hex view!
in the hex view tab of the response, the text that i can see in the right column is exactly showing in the same wrong way as I see it in my program.

I would like to understand how the text shown in the right column of the hex vie tab of the response is treated/transformed by Fidler so as to become the correct text shown in the other tabs. If  i could understand that, I think I could apply the same tranformation on the wrong text that I get in my app.

thanks for the help

Hi Antonello,

 

The HexView in Fiddler was based on an early fork of the HexBEditor control.
However, the issue looks related to how the requests are encoded in your WinHttp application. Refer to this SO thread for details on what might be causing the issue with the unusual characters.
