Hi all,

I am new to C# and currently writing a Nntp client to read article
from a chinese newsgroup. I am curious how to decode the chinese
character using streamreader and display it properly on Win2K and
WinXP?

I have tried the following:

// send XOVER commands to get the header XOVER 1234-1234

// read the header (subject, from, date, arthur)
Streamreader sr = new Streamreader(nntpStream, Encoding.Default); //
1
string str = sr.ReadLine();
listbox.Item.Add(str);

the output of 3 will shows some wierd characters. I tried changing the
encoding to UTF7/UTF8/Unicode, on both win2k and winXP, it is still
showing wierd characters.

Can anyone show me how to read and decode and display the chinese
character properly? Thanks

Kaede

Well, for one, you should be examining the charset returned in the
Content-Type header(assuming it is set in the message).

However, the best default would probably be a strictly Chinese encoding. I
believe Big5 is one, you'll have to look up any others.

Do you know how do I set the encoding to Big5? Should I used
StreamReader using Encoding.Default to examine the Content-Type. Then,
open another streamReader with the appropriate encoding to get the
article?

Do you know of any sample code that show me how to do that?

Thanks very much

Encoding.GetEncoding("Big5"); I think
StreamReader using Encoding.Default to examine the Content-Type. Then,

That I am not sure about. I think the character set for mime headers is set,
but I really don't know for sure, -_-.

Big5, however, is likely compatible with ASCII in its lower 7 bits, much as
most other encodings are.
