blok Unicode (U+FFF0-FFFF) yang berisi beberapa kontrol anotasi interlinear dan karakter pengganti, serta dua titik kode khusus yang secara permanen dicadangkan sebagai nonkarakter di akhir bidang kodenya

Specials adalah blok Unicode terakhir yang memiliki rentang titik kode U+FFF0–FFFF.[2] Blok ini berjumlah 16 buah, tetapi hanya lima titik kode yang dipakai sejak Unicode 3.0.[3][4] Salah satu titik kode yang terkenal adalah � (U+FFFD) yang digunakan untuk mengganti karakter yang tidak diketahui, tidak dikenali, atau yang tidak dapat direpresentasikan.[5]
