U+0697 "ڗ" Arabic Letter Reh with Two Dots Above Unicode Character

U+0697 "ڗ" Arabic Letter Reh with Two Dots Above is a glyph used in the Arabic script, specifically representing a variant of the letter "Reh" (ر) distinguished by two dots placed above the character. This letter is primarily employed in certain non-standard or historical orthographies, such as in some African languages like Hausa or in archaic Persian texts, where it may denote a different phonetic value, often a voiced retroflex or dental flap sound, distinct from the standard Arabic "ra". It is not a common character in mainstream Modern Standard Arabic or standard Persian, but it appears in specialized linguistic contexts, manuscripts, and digital representations of specific dialects and transliteration systems.
