U+0EC4 "ໄ" Lao Vowel Sign Ai Unicode Character

Unicode Version 17.0

U+0EC4 "ໄ" Lao Vowel Sign Ai is a combining mark used in the Lao script to represent the long vowel sound "ai," akin to the "ai" in the English word "sigh." This character is attached to the left side of a consonant letter, where it serves as a preceding vowel sign that modifies the consonant's inherent vowel. It is an essential component in writing many common Lao words, such as ໄທ (Thai) and ໄຟ (fire), and is distinct from the short vowel sign "ໃ" (U+0EC3), which represents a different vowel quality. The character is encoded in the Unicode Standard as part of the Lao block, and its correct rendering depends on proper font support and text shaping for the Lao script's left-to-right directionality.
