The Wikipedia has the following information about this codepoint:

The Old Italic scripts are a family of ancient writing systems used in the Italian Peninsula between about 700 and 100 BC, for various languages spoken in that time and place. The most notable member is the Etruscan alphabet, which was the immediate ancestor of the Latin alphabet used by more than 100 languages today, including English. The runic alphabets used in Northern Europe are believed to have been separately derived from one of these alphabets by the 2nd century AD.
