Fullwidth Latin Small Letter E

Choose Full-width Alphanumeric in a Japanese IME. On Windows, as of 2026, Microsoft Japanese IME uses F9 for Full-width Alphanumeric and F10 for Half-width Alphanumeric.

The encoding history of fullwidth Latin letters includes Japan's JIS C 6226, later known as JIS X 0208, from 1978. It placed Latin letters in a character-set environment built to handle Japanese text alongside double-byte characters. The width convention helped align mixed-width text and supported conversion between legacy encodings; it did not give e a new sound. The ordinary e is its narrow compatibility counterpart.

What does ｅ mean when someone sends it?

Read it as lowercase e; the width is the extra choice. Among fullwidth letters such as ＡＢＣ or ａｂｃ, it belongs to a fullwidth Latin run. If it appears by itself in ordinary text, it may come from input conversion, pasted text, or styling; the glyph alone does not establish a special tone.

Fullwidth describes a text-width convention, not an exact pixel measurement: the font and layout affect how wide it looks. NFKC and NFKD compatibility normalization can fold ｅ to ordinary e. In a username or form value, the two characters may remain distinct until the receiving system applies its own rules.
