U+1EC4 "Ễ" Latin Capital Letter E with Circumflex and Tilde Unicode Character

U+1EC4 "Ễ" Latin Capital Letter E with Circumflex and Tilde is a precomposed Vietnamese character used to represent the distinctive tonal and vowel quality of the Vietnamese language, specifically found in the southern dialect. It combines a base Latin capital letter E with a circumflex accent, which modifies the vowel sound to indicate a higher or gliding tone, and an additional tilde, which marks the rising-falling "ngã" tone. This character is part of the Latin Extended Additional block and is essential for proper spelling in Vietnamese, appearing in words such as "lễ" (meaning ceremony or holiday) to convey precise pronunciation and meaning.
