Combining Right Arrowhead and Up Arrowhead Below

Combining Right Arrowhead and Up Arrowhead Below at U+0356 is a nonspacing diacritic that attaches beneath the preceding character, adding a small right-pointing arrowhead followed by an upward arrowhead below it. It belongs to the Combining Diacritical Marks block and is not meant to appear as an independent symbol. Its main real-world use is in specialist phonetic and linguistic transcription, where below-letter arrow marks can record fine articulatory or tonal details that ordinary spelling does not show. You may encounter it in narrow transcription, field notes, or scholarly descriptions of speech sounds when an author needs a compact mark tied directly to a base letter. Because it is a combining mark, the practical issue is placement: it modifies the character before it, and if inserted after a space or copied without its base letter it may look misplaced or attach to an unintended character. Font and text-layout support for this particular stacked arrowhead mark is less common than for accents such as acute or tilde, so alignment can vary in linguistic documents and databases.
