What ｒ means
It is lowercase r set in a fullwidth character cell.
In Japanese computing, zenkaku means fullwidth and hankaku means halfwidth: the terms distinguish character-cell width, not letter value. ｒ is the fullwidth r; plain r is its narrow counterpart. Japan's JIS C 6226-1978, a standard for exchanging text, included Latin letters alongside Japanese characters. That is an early milestone in the standards lineage: fullwidth Latin forms helped align mixed-width text and retain both widths as systems exchanged data.
As of 2026, Microsoft's Japanese IME uses F9 to convert selected input to full-width alphanumeric characters.
How do I type fullwidth r?
Use a Japanese IME's full-width alphanumeric conversion.
A Japanese IME (input method editor) can produce fullwidth Latin characters as you type; changing the font size only changes how they look.
Is ｒ different from ordinary r?
It is the same letter in a different width form.
Plain r is the narrow counterpart; ｒ is the fullwidth counterpart. Unicode defines it as a width-compatibility form of basic Latin r.
Unicode classifies it as fullwidth, but the font and layout system affect its visible spacing.
Tone: typographic; the fullwidth form marks spacing in mixed-width text.
Use ordinary r in fields that expect the narrow Latin form; a width-sensitive check can reject ｒ.

Questions people ask
1Will software treat ｒ and r the same?
Sometimes. If software applies Unicode's NFKC normalization, it converts ｒ to r; a character-by-character comparison can still tell the forms apart.
