Question:

Chilkat HTTPSpecial characters

Oct 14 '14 at 10:10

Hi,

I've a program that checks a VAT number on a webservice. If the number is OK, then i receive some information about the number. Most of the times, it works, but sometimes, I can't download the answer from the webservice. When the download failed, I discovered that the answer contains special characters like 'ü,é,à,@,....'

I think chilkat struggles with this special characters.

Are there any settings for this characters, or things I can do to make it work?

Answer

Please provide more information, such as a code snippet, the contents of the LastErrorText, and if you set the http.SessionLogFilename property, you can get the exact HTTP request/response. Please provide that information also..
