What is the exact BOM value (what UTF is indicated by it and does it match the encoding specified in XML prolog? If this is UTF-8, you can work without BOM as all characters in the prolog are ASCII and the ASCII code and UTF-8 code are identical in the ASCII subset of the characters.

hi SA,

this is the value i mean code for the char Ã¯Â»Â¿<

Not clear. There are several characters here. What do you mean code? Each character has its Unicode code point, but the code point are represented on the computer using different UTFs. As simple as that. For example, when you type them in this page, they are represented as UTF-8, where each character takes different number of bytes. I think you problem is to understand your problem.

Learn some HTML. You need to use character entities. Besides, you code should not contain data.

In XmlWriterSettings, try ConformanceLevel property as below. If the writer detects any information items that would violate the specified level of conformance, it throws an exception. In some cases, the writer automatically corrects the conformance error.

C#

XmlWriter xmlWrite;
XmlWriterSettings settings = new XmlWriterSettings();
settings.ConformanceLevel = ConformanceLevel.Fragment;
settings.OmitXmlDeclaration = true;

Here[^] is a method that you can use to validate special characters on your XML. The only drawback of this is that if you have plenty of nodes on your XML, it might take time to validate all of them, since what happens here is that, you are checking every character of the value of each of the node.
