Soyombo Subjoiner (U+11A99) is a Unicode nonspacing mark from the Soyombo block. It resides on Plane 1 (SMP, Supplementary Multilingual Plane), has bidirectional class NSM (nonspacing mark), is not mirrored, and has combining class 9 (Virama). In HTML it can be written as 𑪙 or 𑪙. Because it is outside the Basic Multilingual Plane, proper font support is required; otherwise a fallback box may be shown.
