Hi David, Thanks for the update. I translated the characters from UCS-2 to UTF-8 using C APIs. Actually i took these chinese characters(您是如) from Goolge Translate and used in xml file to test the unicode support.When i translated these characters from UCS-2 to UTF-8 using C APIs, i got these characters(귦꺡髧). Now i am not getting the errors from xerces parser.
But i have a question. Will the characters themselves change from one format to another format? If i have a string "abcd", will it change from one format to another format? I understand the encoding in different formats is different but i do not understand why the characters themselves are chaning from one format to another format. Any information related to this will be a great help to me. Thanks, Jaya Nageswar.
