Decode Chinese Character From UTF-7 Data

Hi group,

I am writing a RFC Server with SAP.NET Connector to connect to SAP. There
are chinese characters passing back and forth.

I found that all chinese characters sending from SAP are encoded with
UTF-7. In order to let SAP display chinese characters correctly, i also need
to encode my chinese data by UTF-7.

However, i need to convert the UTF-7 encoded SAP data back to chinese
character, but i tried in vain. I wrote a simple program to test it. but it
made me more confused. The following C# program try to encode the chinese
string "s" with UTF-7 and then decode it.

But i never get it back. What is wrong?



=============== =============== ==============
using System;
using System.Text;
namespace ConsoleApplicat ion1
class Class1
static void Main(string[] args)

string s = "??";

string encoded_s;
string restored_s;

Console.WriteLi ne("Source String : [{0}]" , s);

encoded_s=UTF7E ncoder(s);
Console.WriteLi ne("Encoded String : [{0}]" , encoded_s);

restored_s=UTF7 Decoder(encoded _s);
Console.WriteLi ne("Decoded String : [{0}]" , restored_s);

Console.ReadLin e();

public static string UTF7Encoder(str ing src)
return CodeConverter(s rc,Encoding.Def ault,Encoding.U TF7);

public static string UTF7Decoder(str ing src)
return CodeConverter(s rc,Encoding.UTF 7,Encoding.Defa ult);

private static string CodeConverter(s tring src, Encoding src_encoding,
Encoding dest_encoding)
byte[] array = new byte[src.Length];
array = src_encoding.Ge tBytes(src);
string s = dest_encoding.G etString(array) ;
return s;

Hi Alex,

Your code is correct, however, it will not work for me as my Default encoding doesn't support chinese characters. Changing Encoding.Defaul t to Encoding.Unicod e fixed that, which may be your solution as well.

Happy Coding!

The following 4 lines of code parses an XML document very well if the XML document contains only English words.

This is the complaint of Python:

I have some unicode string with some characters encode using python notation like '\n' for LF. I need to convert that to the actual LF character. There is a 'unicode_escape' codec that seems to suit my purpose. >>> encoded = u'A\\nA' >>> decoded = encoded.decode('unicode_escape') >>> print len(decoded) 3 Note that both encoded and decoded are unicode string.

I use chinese charactors as an example here. "'\\xc4\\xe3\\xba\\xc3\\xc2\\xf0'" My first question is : what strategy does 'decode' use to tell the way to seperate the words. I mean since s1 is an multi-bytes-char string, how did it determine to seperate the string every 2bytes or 1byte? My second question is: is there any one who has tested very long mbcs
