A broad badge for anyone needing assistance, against a narrower one naming a specific class of internal disability.
The help mark is deliberately broad: it says the wearer may need assistance and says nothing about why, which is what makes it usable by people who do not wish to disclose a condition. The heart plus mark is specific to internal disability — the heart and organ conditions the badge was created for. Someone wearing the heart plus mark is making a narrower statement than someone wearing the help mark.
The narrower internal-disability badge it overlaps.
| Japanese help mark | Japanese heart plus mark | |

| Relationship (from Symbolwise's records) | Commonly confused with Japanese heart plus mark — The narrower internal-disability badge it overlaps. | Commonly confused with Japanese help mark — The broader badge with which it overlaps and is constantly conflated. |
JIS Z 8210: Public Information Symbols
Japanese Industrial Standards Committee · retrieved 2026-08-27
The Japanese national standard for public guidance pictograms, cited for the identity and drawn form of each symbol in it. The standard is harmonised with ISO 7001 in part and diverges in part; where a record concerns a Japanese-only symbol the divergence is stated in the record rather than assumed.
Both are drawn as one continuous decorative stroke with a closed loop and a tail that crosses back over itself, which is why a description of the shape alone reaches both. The clef is far taller, spans a stave, and its spiral encircles one specific line — that encircled line is the note G, and it is the only reason the shape is drawn where it is.
The ampersand is a ligature of the Latin word et, still visible in some italic forms where the e and the t can be picked out. The Tironian et is a separate mark descending from a Roman shorthand, shaped like a small seven, and it is in daily public use in Ireland as the written form of 'agus'. A reader who knows only the ampersand takes the other for a numeral, which on a bilingual road sign produces a confidently wrong place name.
A building's assembly point is a safe place to stand once you are outside. A ship's muster station is a staffed step in a procedure: you are counted against a roll, briefed, and if necessary allocated to a survival craft, which is why it has a letter or a number and appears on your cabin door card. Both are green, both show grouped figures, and both are called an assembly point in ordinary speech — and treating a muster station as somewhere merely to wait is the misunderstanding drills exist to correct.
As punctuation the asterisk points at a footnote or marks a required field. In a filename pattern typed at a shell it matches any run of characters, including none — and the shell expands it against real filenames before the command runs, so the command never sees the pattern at all. That expansion is the part people are surprised by.
