I am developing an application in which i want to encode the Spanish text. But the problem is that,it doesn't encode the special characters such as á, é, í, ó, ú, ü,Á, É, Í, Ó, Ú, Ü,Ñ,ñ . How can i do this?i want to encode-decode the spanish text.

回答1:

For international support using simple UTF-8 encoding to encode/decode your data should be enough.

Utf-8 has a beautiful capability to be able to read ASCII with one byte, as ordinary ASCII, and Unicode characters with 2 bytes. So it's able "to shrink" when it's necesary.

For complete C# documentation look on UTF-8

EDIT

  Encoding enc = new UTF8Encoding(true, true);
  string value = " á, é, í, ó, ú, ü,Á, É, Í, Ó, Ú, Ü,Ñ,ñ "; 
  byte[] bytes= enc.GetBytes(value); //convert to BYTE array 

 //save in some file 

 //after can read  from the file like
 string decodedString = enc.GetString(byteArrayReadFromFile);

ok,I am answering my own question ,Hope it will help someone; to print spanish or any other non-ascii character in the given string replace all non-ascii characters by their unicode escape character set E.g repalce á by \u00e1 And then simply print the string.

i.e

string str="árgrgrgrááhhttá";
str=str.Replace("á", "\u00e1");
