1.I picked up this on net where it is said: if it falls into exception, then file is not UTF8.
2.It does not go into exception.
3. Until I figured that I should use cp1250 instead of UTF8, nothing was ok
Any advice how to catch wrong encoding exception ?
Well, there's an UnsupportedEncodingException that you could catch, but that's for encodings not supported by your system at all. Using a supported encoding that just isn't right for the file you're reading isn't going to cause an exception of any kind. Where did you see that?
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
