'''Halfwidth and Fullwidth Forms Supplement''' is the name of a [[Unicode block]] U+1AB50FF00&ndash;1ADFFFFEF, provided so that older encodings containing both [[Halfwidth and fullwidth forms|halfwidth and fullwidth]] characters can have lossless translation to/from Unicode. It is the second-to-last block of the [[Basic Multilingual Plane]], followed only by the short [[Specials (Unicode block)|Specials]] block at U+FFF0&ndash;FFFF. Its block name in Unicode 1.0 was '''Halfwidth and Fullwidth Variants'''.<ref>{{cite web |url=https://www.unicode.org/versions/Unicode1.0.0/CodeCharts2.pdf |work=The Unicode Standard |version=version 1.0 |title=3.8: Block-by-Block Charts |publisher=[[Unicode Consortium]]}}</ref>

Range U+FF01&ndash;FF5E reproduces the characters of [[ASCII]] 21 to 7E as fullwidth forms. U+FF00 does not correspond to a fullwidth ASCII 20 (space character), since that role is already fulfilled by U+3000 "[[ideographic space]]".
