        "content": "In Unified English Braille (UEB), the symbol \u201c@\u201d (the commercial \u201cat\u201d sign) is represented by a two-cell sequence: the prefix **dots-4** followed by the letter **a** (which is dot-1). ([brailleauthority.org](https://www.brailleauthority.org/ueb/NZ%20UEB%20Manual%202011.pdf?utm_source=openai))\n\nHere\u2019s how to interpret that:\n\n- **First cell (\u201cprefix\u201d)**: dot-4 (just the upper right dot of the standard 6-dot cell).  \n- **Second cell**: dot-1 (the upper left dot of the cell, which normally represents the letter \u201ca\u201d).  \n\nTogether, \u2808\u2801 represents \u201c@\u201d. ([brailleauthority.org](https://www.brailleauthority.org/ueb/NZ%20UEB%20Manual%202011.pdf?utm_source=openai))\n\nIf you need the \u201ccomputer braille\u201d version (used for ASCII-like symbol entries or in some electronic braille systems), it may differ slightly depending on the specific code or locale.
