U+1E5F "ṟ" Latin Small Letter R with Line Below Unicode Character

U+1E5F "ṟ" Latin Small Letter R with Line Below is a grapheme used primarily in the transliteration of certain languages and alphabets, most notably in the transcription of Sanskrit and other Indic scripts where it represents a retroflex or hard r sound. The diacritical mark, a line placed beneath the letter, distinguishes it from a standard "r" and signals a specific phonetic quality that is critical for accurate linguistic representation. Although it is not a common character in everyday English or most Western European languages, it appears in scholarly works, dictionaries, and language learning materials focused on Dravidian, Indo-Aryan, or other language families that require precise consonant notation.
