'''Halfwidth and Fullwidth Forms''' is
Range U+FF01–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]]".
Range U+
The range U+FFA0–FFDC encodes halfwidth forms of [[Hangul Compatibility Jamo|compatibility jamo]] characters for [[Hangul]], in a transposition of their [[KS C 5601#1974|1974 standard]] layout. It is used in the mapping of some IBM encodings for Korean, such as IBM code page 933, which allows the use of the [[Shift Out and Shift In characters]] to shift to a double-byte character set.<ref name="ibm933">{{cite web|url=http://demo.icu-project.org/icu-bin/convexp?conv=ibm-933|title=ICU Demonstration - Converter Explorer
Range U+FFE0–FFEE includes fullwidth and halfwidth symbols.
