U+0E3A "ฺ" Thai Character Phinthu Unicode Character

U+0E3A "ฺ" Thai Character Phinthu is a combining mark used in the Thai script to indicate that a consonant is silent or to serve as a diacritical marker, primarily appearing below the base character. It is an invisible or null consonant sign, often employed in transliterations of Pali and Sanskrit texts where a consonant needs to be represented without an inherent vowel sound, or to correct the spelling of certain Thai words derived from these ancient languages. Though rarely used in modern everyday Thai writing, it remains a key component for accurately rendering liturgical and historical texts, ensuring precise pronunciation and orthography.
