Segmented Digit Six

It is the ordinary decimal six in a distinctive, blocky seven-segment design. A seven-segment display builds digits from straight bars, like on a digital clock.

The Atari ST was a personal-computer line launched in 1985. Its character set stored these digits in separate slots, and applications used them especially for game scores.

For a multi-digit number, use matching segmented digits in every position; one ordinary numeral breaks the visual run.

Can NFKC erase the display style?

Yes; NFKC can replace the style with ordinary 6.

NFKC is a text-cleanup form that folds formatting distinctions so characters compare alike. It changes 🯶 to plain 6; NFC normalization keeps the two characters distinct. The number stays six, but the segmented design is lost.
