The Wikipedia has the following information about this codepoint:
Pe is the seventeenth letter of the Semitic abjads, including Phoenician pē 𐤐, Hebrew pē פ, Aramaic pē 𐡐, Syriac pē ܦ, and Arabic fāʾ ف (in abjadi order).
The original sound value is a voiceless bilabial plosive /p/ and it retains this value in most Semitic languages, except for Arabic, where the sound /p/ changed into the voiceless labiodental fricative /f/, carrying with it the pronunciation of the letter.
Not to be confused with the Turned g.
The Phoenician letter gave rise to the Greek Pi (Π), Latin P, and Cyrillic П.
