Unicode Version 17.0
Р
U+0420 "Р" Cyrillic Capital Letter Er is the uppercase form of the twenty-first letter in the Cyrillic alphabet, representing the consonant sound /r/ as in the English word "run." Visually identical to the Latin capital letter P, it serves as a key component in many Slavic and non-Slavic languages that use the Cyrillic script, including Russian, Bulgarian, and Serbian, where it appears in words such as "Россия" (Russia) and "река" (river). Its historical derivation traces back to the Greek letter rho (Ρ), reflecting the shared roots of the Cyrillic and Greek alphabets through the work of early medieval scribes.
