What ﹳ means
It is stored typography from old Arabic data systems.
The paper trail starts with a 2001 IBM/Unicode proposal: the fragment appears in the IBM-420, IBM-1046 and IBM-864 code pages, including EBCDIC host databases, where it served one-to-one exchange with data that already existed. Committees accepted it as a backward-compatible mapping, not a new piece of Arabic writing.
So the meaning is practical, not expressive: a named typographic component rather than a word, punctuation or signal. For anything new, spell the ordinary Arabic letters — the renderer builds the fancy strokes itself.
Why does it look like a real Arabic mark?
Because a sweeping tail is a real piece of Arabic typography.
Old systems stored that stroke as a character; modern engines draw it from the letters around it, so the fragment survives mostly as residue in converted files. One exception is a design feature, not a rule: Sakkal Saad Poster's 2025 guide uses FE73 after a kashida for custom-length swash extensions.
A 2020 Unicode proposal documented a different sign on the same idea — an Arabic vertical tail used as an abbreviation marker in early Persian movable-type printing — and carefully separated it from FE73. Same silhouette, different job.
Technical and archival; inside a new Arabic sentence it reads as encoding machinery, not style.
Don't drop it into text as a generic Arabic stretch mark — a font feature is not a writing standard.

2Why did this appear after converting an old Arabic file?
Probably conversion residue. IBM's Arabic code pages stored the fragment as a character, so a converter may keep it rather than rebuild the underlying letters.
Is it still needed in new Arabic documents?
No. Modern shaping composes tails and elongation from ordinary letters; the fragment matters only when old files or databases are converted.
