You should sanitize xml data here is what characters can be used inside http://en.wikipedia.org/wiki/Valid_characters_in_XML valid characters will be

public string sanitizeText(string sanitize){
    StringBuilder result = new  StringBuilder();
    foreach(   char x in sanitize){
        if ((x == 0x9 || x == 0xA || x == 0xD) ||   
        ((x >= 0x20) && (x <= 0xD7FF)) ||   
        ((x >= 0xE000) && (x <= 0xFFFD)) ||   
        ((x >= 0x10000) && (x <= 0x10FFFF)))  result.Append(x);
    } 
    return result.ToString();
}
