// If "guessUnicodeChars=1" and if this library is compiled in UNICODE 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
// UNICODE before being parsed. If "guessUnicodeChars=0", no conversion will
// be performed.
//
// If "guessUnicodeChars=1" and if this library is compiled in ASCII/UTF8 mode, then the
// "parseFile" and "openFileHelper" functions will test if the file contains UNICODE
// characters. If this is the case, then the file will be loaded and converted in memory to
// ASCII/UTF8 before being parsed. If "guessUnicodeChars=0", no conversion will
// be performed
//
// Sometime, it's useful to set "guessUnicodeChars=0" to disable any conversion
// because the test to detect the file-type (ASCII/UTF8 or UNICODE) may fail (rarely).
//
// About the "strictUTF8Parsing" parameter:
// If "strictUTF8Parsing=0" then we assume that all characters have the same length of 1 byte.
// If "strictUTF8Parsing=1" then the characters have different lengths (from 1 byte to 4 bytes)
// depending on the content of the first byte of the character.

// First of all, you most-probably will never have to use this function.
// This function try to guess if the character encoding is UTF-8. It then returns the appropriate
// value of the global parameter "strictUTF8Parsing" described above. The guess is based on the
// content of a buffer of length "bufLen" bytes that contains the first bytes (minimum 25
// bytes; 200 bytes is a good value) of the file to be parsed. The "openFileHelper" function is
// using this function to automatically compute the value of the "strictUTF8Parsing" global parameter.
// There are several heuristics used to do the guess. One of the heuristic is based on "encoding"
// attribute. The original XML specifications forbids to use this attribute to do the guess but
// you can still use it if you set "useXMLEncodingAttribute" to 1.
