    * A majority of mainframes *and networking protocols* are BigEndian
    * A majority of micro chips (ie, Intel) are little endian.

## Notes ##

* BOM Examples:
    * FF FE: UCS-2LE or UTF-16LE ((http://codesnipers.com/?q=node/68))
    * FE FF:  UCS-2BE or UTF-16BE ((http://codesnipers.com/?q=node/68))
    * EF BB BF  UTF-8 ((http://codesnipers.com/?q=node/68))


### XML / Unicode 

* The BOM is not guaranteed to be in every Unicode file. 
* The BOM is not necessary in XML files: because the Unicode encoding can be determined from the leading less than sign.
    * Can be determined from first characters of Xml:
        * 3C 00  UCS-2LE or UTF-16LE
        * 00 3C  UCS-2BE or UTF-16BE
        * 3C XX  UTF-8 (where XX is non-zero)


<WRAP important>
Without contextual information, a BOM, or a file type standard with a header like XML and HTML, a file should be assumed to be in the default system locale ANSI code page, governed by the Language for non-Unicode Programs in the Regional Settings on the computer on which it is found.
