U+FF7B "サ" Halfwidth Katakana Letter Sa Unicode Character

Unicode Version 17.0

U+FF7B "サ" Halfwidth Katakana Letter Sa is a typographic variant of the fullwidth Katakana character サ, used primarily in contexts where text must fit into a fixed number of monospaced character cells, such as in legacy computer terminals, teletext systems, or older Japanese video games. It represents the syllable "sa" and occupies exactly half the horizontal width of a standard CJK (Chinese, Japanese, and Korean) fullwidth character, allowing it to be easily combined with Latin halfwidth characters in mixed-width text environments. This character is part of the Halfwidth and Fullwidth Forms Unicode block and was introduced to ensure compatibility with older encoding standards like JIS X 0201, which required a narrower katakana set for efficient display on limited hardware.
