U+FF6F Halfwidth Katakana Letter Small Tu

U+FF6F 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 Small Tu. 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+FF6F prohibits line breaks before its position. There are some exceptions, though.

The Wikipedia has the following information about this codepoint:

The sokuon (促音) is a Japanese symbol in the form of a small hiragana or katakana tsu, as well as the various consonants represented by it. In less formal language, it is called chiisai tsu (小さいつ) or chiisana tsu (小さなつ), meaning "small tsu". It serves multiple purposes in Japanese writing.
