RUNIC LETTER D

The Runic block encodes the letters of the futhark alphabets used across Scandinavia and the British Isles before Latin script displaced them, and U+16D1 is its D. Unicode assigns it the general category Lo (letter, other), the class used for scripts that draw no distinction between upper and lower case. Runic letters were cut into wood, bone, and stone, which is why their strokes are predominantly straight and angular: curves are difficult to carve along a grain. The block unifies letters that served several related alphabets and historical periods, so a single code point may correspond to more than one transliteration depending on the inscription being represented.
