UTF-8 is a character encoding standard used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode Transformation Format – 8-bit. [1] Almost every webpage is stored in UTF-8. UTF-8 supports all 1,112,064 [2] valid code points using a variable-width encoding of one to four one-byte (8-bit) code units.
The Arrows block contains eight emoji: U+2194–U+2199 and U+21A9–U+21AA. [3] [4]The block has sixteen standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the eight emoji, all of which default to a text presentation.
The same character converted to UTF-8 becomes the byte sequence EF BB BF. The Unicode Standard allows the BOM "can serve as a signature for UTF-8 encoded text where the character set is unmarked". [76] Some software developers have adopted it for other encodings, including UTF-8, in an attempt to distinguish UTF-8 from local 8-bit code pages.
