    // set an unrecognized encoding then the return value will be "1" to signal an error.
    //
    // About the "guessWideCharChars" parameter:
    //     If "guessWideCharChars=1" and if this library is compiled in WideChar mode, then the
    //     "parseFile" and "openFileHelper" functions will test if the file contains ASCII
    //     characters. If this is the case, then the file will be loaded and converted in memory to
    //     WideChar before being parsed. If "guessWideCharChars=0", no conversion will
    //     be performed.
    //
    //     If "guessWideCharChars=1" and if this library is compiled in ASCII/UTF8/char* mode, then the
    //     "parseFile" and "openFileHelper" functions will test if the file contains WideChar
    //     characters. If this is the case, then the file will be loaded and converted in memory to
    //     ASCII/UTF8/char* before being parsed. If "guessWideCharChars=0", no conversion will
    //     be performed
    //
    //     Sometime, it's useful to set "guessWideCharChars=0" to disable any conversion
    //     because the test to detect the file-type (ASCII/UTF8/char* or WideChar) may fail (rarely).
    //
    // About the "characterEncoding" parameter:
    //     This parameter is only meaningful when compiling in char* mode (multibyte character mode).
    //     In wchar_t* (wide char mode), this parameter is ignored. This parameter should be one of the
    //     three currently recognized encodings: XMLNode::encoding_UTF8, XMLNode::encoding_ascii,
    //     XMLNode::encoding_ShiftJIS.
    //
    // About the "dropWhiteSpace" parameter:
    //     In most situations, text fields containing only white spaces (and carriage returns)
    //     are useless. Even more, these "empty" text fields are annoying because they increase the
    //     complexity of the user's code for parsing. So, 99% of the time, it's better to drop
    //     the "empty" text fields. However The XML specification indicates that no white spaces
    //     should be lost when parsing the file. So to be perfectly XML-compliant, you should set
    //     dropWhiteSpace=0. A note of caution: if you set "dropWhiteSpace=0", the parser will be
    //     slower and your code will be more complex.
    //
    // About the "removeCommentsInMiddleOfText" parameter:
    //     Let's consider this code:
    //        XMLNode x=XMLNode::parseString("<a>foo<!-- hello -->bar<!DOCTYPE world >chu</a>","a");
    //     If removeCommentsInMiddleOfText=0, then we will have:
    //        x.getText(0) -> "foo"
    //        x.getText(1) -> "bar"
    //        x.getText(2) -> "chu"
    //        x.getClear(0) --> "<!-- hello -->"
    //        x.getClear(1) --> "<!DOCTYPE world >"
    //     If removeCommentsInMiddleOfText=1, then we will have:
    //        x.getText(0) -> "foobar"
    //        x.getText(1) -> "chu"
    //        x.getClear(0) --> "<!DOCTYPE world >"

    // file to be parsed. The "openFileHelper" function is using this function to automatically compute
    // the value of the "characterEncoding" global parameter. There are several heuristics used to do the
    // guess. One of the heuristic is based on the "encoding" attribute. The original XML specifications
    // forbids to use this attribute to do the guess but you can still use it if you set
