In the ASCII character encoding, the hyphen is character 45. As Unicode is identical to ASCII (the 1967 version) for all encodings up to 127, the number 4510, i.e. 2D16, is assigned to this character in Unicode. As the character is also used as a minus sign, it is formally denoted U+002D - HYPHEN-MINUS. Unicode also encodes the minus and hyphen separately, as U+2212 and U+2010 respectively. However, as the Unicode hyphen is inconvenient to enter on most keyboards and the glyphs for the Unicode hyphen and the hyphen-minus are identical in most fonts (Lucida Sans Unicode is one of the few exceptions), use of the hyphen-minus as the hyphen character is very common. Even the Unicode Standard regularly uses the hyphen-minus rather than the Unicode hyphen.
