U+1D18A "𝆊" Musical Symbol Combining Double Tongue Unicode Character

U+1D18A "𝆊" Musical Symbol Combining Double Tongue is a specialized diacritical mark used in Western musical notation to indicate a double tonguing technique for wind instruments, primarily for rapid, articulated passages on flutes, trumpets, or other brass and woodwind instruments. Visually, it resembles a small, slanted slash or short wavy line placed above a notehead, and it typically combines with a note symbol to instruct the performer to articulate the note using a quick "ta-ka" or "tu-ku" syllable pattern for faster execution.
