Overview

Japanese text encoded in the halfwidth katakana range handles voicing differently from ordinary Japanese, and U+FF9E is the reason. In fullwidth Japanese the dakuten is a combining mark that sits on the preceding kana; here it is an independent spacing character that occupies its own cell and follows the kana it modifies. That design came from JIS X 0201, the single-byte standard used by early terminals, receipt printers, and telecoms equipment, where every character had to occupy exactly one fixed-width column. Unicode preserves the behaviour by classifying it Lm (modifier letter) inside the Halfwidth and Fullwidth Forms block. Normalisation matters as a result: a halfwidth kana followed by this mark maps to the corresponding precomposed fullwidth kana under NFKC.
