Ṟ
U+1E5E "Ṟ" Latin Capital Letter R with Line Below is a specialized diacritical letter used primarily in the transliteration of certain languages and phonetic alphabets, such as in representing retroflex or emphatic consonant sounds found in some South Asian and African languages. The line beneath the standard Latin capital R visually marks a distinct articulation, often contrasting with its unmodified counterpart in linguistic notation. This character is part of the Latin Extended Additional block and is encoded for digital text to ensure accurate representation of these specific phonetic or orthographic distinctions, particularly in academic, historical, or liturgical contexts.
