U+0210 "Ȑ" Latin Capital Letter R with Double Grave Unicode Character
Unicode Version 17.0
Ȑ
U+0210 "Ȑ" Latin Capital Letter R with Double Grave is a rarely used typographic variant of the capital letter R, distinguished by two stacked grave accent marks instead of one. This diacritic, known as the double grave, indicates a specific phonological or prosodic feature, most notably employed in the historical or scholarly transcription of certain Slavic languages, such as Serbo-Croatian, where it can denote a falling tone or a distinct syllabic pronunciation of the letter R. Its inclusion in Unicode preserves a specialized character for linguistic notation and typesetting, ensuring that texts requiring precise tonal or stress marking can be accurately represented in digital form.
