U+16D4 "ᛔ" Runic Letter Dotted-P Unicode Character

U+16D4 "ᛔ" Runic Letter Dotted-P is a glyph within the Runic block, specifically representing a variant of the runic letter P that has been modified with a diacritical dot to indicate a different phonetic value, often used in certain medieval Scandinavian inscriptions to denote a bilabial fricative sound similar to modern "f" or "v" rather than the standard plosive "p". This dotted form appears in later runic alphabets, such as the Younger Futhark, where it helped to adapt the writing system to the evolving sounds of Old Norse and other Germanic languages. The rune itself is part of a broader set of dotted runes introduced to increase the efficiency of writing by distinguishing voiceless and voiced dental or labial consonants.
