Chakma digit four

It represents the number four in Chakma writing.

It is one of the native digits 0–9 used with the Chakma script. The dated examples span 1903, 1982, and 2004. In that order, they include a Chakma chart in Grierson's Linguistic Survey of India, a language reference work; a digit chart in Cāṅmār āg pudhi; and writing examples in Phagadāṅ.

The value stays four, but the writing system can differ: some Chakma writing uses Bengali digits, while Myanmar digits also appear in Tanchangya writing. The Chakma and Myanmar scripts are closely related, but their digits remain separate characters.

Why can its shape vary or disappear?

Regional forms and font coverage can change what you see.

The Unicode encoding proposal records regional variation between India and Bangladesh, including rounder forms. A font without Chakma coverage may show an empty box. In 2026, an Ubuntu-focused layout included Noto Sans Chakma because its documentation said Ubuntu's built-in Noto coverage missed some Chakma glyphs.

How do I type it?

Use a Chakma keyboard layout.

The Institute of Policy Dynamics Linux layout puts Chakma digits on unshifted number keys and plain ASCII digits—the ordinary 0–9 set—on AltGr. Unicode's CLDR 43 keyboard chart lists this character on the Windows Chakma layout's 4 key.
