Old Chinese Hook Mark (U+16FE2) is a Unicode other punctuation from the Ideographic Symbols and Punctuation block. It resides on Plane 1 (SMP, Supplementary Multilingual Plane), has bidirectional class ON (other neutrals), is not mirrored, and has combining class 0 (Not Reordered). In HTML it can be written as 𖿢 or 𖿢. Because it is outside the Basic Multilingual Plane, proper font support is required; otherwise a fallback box may be shown.
