View source for UTF-8

'''UTF-8''' refers to Unicode Transformation Format 8-bit is a variable-width encoding that can represent every character in the Unicode character set that was designed for backward compatibility with [[ASCII]].

==Overview==
UTF-8 encodes each [[Unicode]] character as a variable number of 1 to 4 octets. The number of octets depends on the integer value assigned to the character.
UTF-8 is the default encoding for XML and has been the dominant character encoding on the web since 2010.<ref>[https://www.utf8.com/ About utf-8]</ref>

[[W3C]] has offered several reasons for the popularity of UTF-8: 
# An HTML page can only be in one encoding, and UTF-8 can support many languages and accommodate many pages and forms.
# Barriers to using Unicode are very low; by January 2012, Google reported that over 60% of the Web in their sample used UTF-8. 
# ASCII is a subset of UTF-8; all ASCII characters in UTF-8 use the same bytes as an ASCII encoding, helping with interoperability. 
# The HTML5 specification says "Authoring tools should default to using UTF-8 for newly-created documents."<ref>[https://www.w3.org/International/questions/qa-choosing-encodings Why choose UTF-8, W3C]</ref>
