Context and question: The UCS-2 and UTF-16 encodings specify the Unicode Byte Order Mark (BOM) for use at the beginnings of text files, which may be used for byte ordering detection (or byte endianness detection). The BOM, code point U+FEFF has the important property of unambiguity on byte reorder, regardless of the Unicode encoding used; U+FFFE (the result of byte-swapping U+FEFF) does not equate to a legal character, and U+FEFF in other places, other than the beginning of text, conveys the zero-width non-break space (a character with no appearance and no effect other than preventing the formation of ligatures).
What specifies the BOM?
Answer: UCS-2 and UTF-16
Context and question: The Bronze Age arrived circa 1500 BC when people in the region were turning copper into bronze, growing rice and domesticating poultry and pigs; they were among the first people in the world to do so. Human remains and artifacts from this era were discovered in Monywa District in the Sagaing Division. The Iron Age began around 500 BC with the emergence of iron-working settlements in an area south of present-day Mandalay. Evidence also shows the presence of rice-growing settlements of large villages and small towns that traded with their surroundings as far as China between 500 BC and 200 AD. Iron Age Burmese cultures also had influences from outside sources such as India and Thailand, as seen in their funerary practices concerning child burials. This indicates some form of communication between groups in Myanmar and other places, possibly through trade.
When did the Age of Iron begin?
Answer:
The Iron Age began around 500 BC
