What ㌟ means
㌟ represents サイクル, Japanese for “cycle.” Its square marks a compact writing format.
It fits a multi-syllable katakana word (katakana is a Japanese sound-based script) into one kanji-sized cell; kanji can represent a word or part of one. Japan's standards lineage for these forms begins with JIS C 6226, a character-encoding standard published in 1978.
What happens when ㌟ is normalized?
It expands to サイクル. Compatibility normalization replaces the compact form with ordinary text, so the square layout disappears.
Font support for ㌟ varies. In vertical Japanese layout, its component characters may be arranged differently from horizontal text. For ordinary Japanese prose, サイクル is clearer.
Questions people ask
1Why does ㌟ show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
