U+FF7F Halfwidth Katakana Letter So

U+FF7F was added in Unicode version 1.1 in 1993. It belongs to the block U+FF00 to U+FFEF Halfwidth and Fullwidth Forms in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Letter and is mainly used in the Katakana script.

The glyph is a narrow version of the glyph Katakana Letter So. Accordingly, its width in East Asian Text is halfwidth. In bidirectional text it is written from left to right. When changing direction it is not mirrored. This katakana joins with other adjacent katakana to form a word. U+FF7F offers a line break opportunity at its position, except in some numeric contexts.

The Wikipedia has the following information about this codepoint:

そ, in hiragana, or ソ, in katakana, is one of the Japanese kana, each of which represents one mora. Both represent [so]. The version of this character used by computer fonts does not match the handwritten form that most native Japanese writers use. The native way is shown here as the alternative form.
