U+FD0B "ﴋ" Arabic Ligature Sheen with Khah Isolated Form Unicode Character

U+FD0B "ﴋ" Arabic Ligature Sheen with Khah Isolated Form is a typographic ligature representing the combined shape of the Arabic letters Sheen (ش) and Khah (خ) when written sequentially in an isolated context, where no other characters connect on either side. It belongs to the Arabic Presentation Forms-A block, a section of Unicode designed to encode precomposed forms for compatibility with older text processing systems and calligraphic styles, rather than for modern plain text use. This character preserves a traditional cursive rendering found in historical manuscripts and specialized fonts, allowing the two letters to merge into a single glyph for aesthetic or space-saving reasons.
