U+0D4C "ൌ" Malayalam Vowel Sign Au Unicode Character

U+0D4C "ൌ" Malayalam Vowel Sign Au is a combining diacritical mark used in the Malayalam script to represent the vowel sound "au," which functions as a dependent vowel sign that attaches to a consonant letter to modify its inherent vowel. It appears as a curved, hook-like symbol extending from the top right of a consonant character, such as in the syllable "കൌ" (kau), and is distinct from the independent vowel form for "au" which has its own separate Unicode code point. In modern Malayalam writing, this sign is essential for accurately spelling loanwords and specific native terms that require the diphthong sound, and it follows the consonant in logical order when encoded in digital text.
