Halfwidth Katakana Letter Se Letter

セ is the halfwidth Katakana letter SE, Unicode U+FF7E.

U+FF7E

セ (U+FF7E) is the halfwidth form of the Katakana letter SE. It’s often used when you need halfwidth characters for layout, compatibility, or styling consistency.

Halfwidth Katakana Letter Se Letter Meaning

セ is Unicode “HALFWIDTH KATAKANA LETTER SE” (U+FF7E). It represents the Katakana sound “se” in a halfwidth presentation, which differs from the standard fullwidth Katakana character “セ” (U+30BB). Because halfwidth characters typically occupy less horizontal space, セ is commonly used in contexts that expect halfwidth Katakana, such as legacy Japanese text encodings, fixed-width layouts, or UI components that were designed around halfwidth glyph widths. In plain text, it’s also useful for matching a specific character width rather than just the phonetic content.

Common uses

  • •Fixed-width UI and form fields that expect halfwidth Katakana
  • •Legacy data display or conversion workflows that preserve character width
  • •Text styling or typography systems where character width must match
  • •Creating consistent alignment in tables that mix Latin and Katakana
  • •Preparing strings for systems that specifically accept halfwidth Katakana
