The Wikipedia has the following information about this codepoint:

The Phoenician alphabet is a consonantal alphabet (or abjad) used across the Mediterranean civilization of Phoenicia for most the 1st millennium BC. It was the first mature alphabet, and attested in Canaanite and Aramaic inscriptions found across the Mediterranean region. In the history of writing systems, the Phoenician script also marked the first to have a fixed writing direction—while previous systems were multi-directional, Phoenecian was written horizontally, from right to left. Its developed directly from the Proto-Sinaitic script used during Late Bronze Age, which was derived in turn from Egyptian hieroglyphs.

The Phoenician alphabet was used to write Canaanite languages spoken during the Early Iron Age, sub-categorized by historians as Phoenician, Hebrew, Moabite, Ammonite and Edomite, as well as Old Aramaic. It was widely disseminated outside of the Canaanite sphere by Phoenician merchants across the Mediterranean, where it was adopted and adapted by other cultures. The Phoenician alphabet proper was used in Ancient Carthage until the 2nd century BC, where it was used to write the Punic language. Its direct descendant scripts included the Aramaic and Samaritanalphabets, several Alphabets of Asia Minor, and the Archaic Greek alphabets.

The Phoenician alphabet proper uses 22 consonant letters—as an abjad used to write a Semitic language, the vowel sounds were left implicit—though late varieties sometimes used matres lectionis to denote some vowels. As its letters were originally incised using a stylus, their forms are mostly angular and straight, though cursive forms increased in use over time, culminating in the Neo-Punic alphabet used in Roman North Africa.
