半形及全形字元 (Unicode區段)
半形及全形字元是 Unicode 基本多文種平面內的最後第二個區段,範圍包括 U+FF00..U+FFEF。本區段包含全形和半形字元以便可以無失真從舊編碼系統轉換至 Unicode。該區段於 Unicode 1.0 的舊稱為 半形及全形變體(Halfwidth and Fullwidth Variants)。[4]

註釋:[1][2][3] |
U+FF01..U+FF5E 編碼了 ASCII 內 21 至 7E 的全形版本。U+FF00 未對應 ASCII 20 (空格)字元,該字元已經由 U+3000 IDEOGRAPHIC SPACE 表意空格取代。
U+FF65..U+FF9F 編碼了JIS X 0201 內的半形片假名——參見半形假名。
U+FFA0..U+FFDC 編碼了諺文KS C 5601 1974年版的諺文相容字母。其對應的字元用於 IBM 的韓文編碼頁 933,其中包括 Shift In 和 Shift Out 的字元以對應雙位元組編碼。[5]基於雙位元組編碼可能包括相容字母,本區段包含了部分半形變體以便可以無失真從 KS C 5601 轉碼至 Unicode。[6][7]
U+FFE0..U+FFEE 編碼了全形及半形符號。
