U+1230B CUNEIFORM SIGN U

The Wikipedia has the following information about this codepoint:

The cuneiform U sign is found in both the 14th century BC Amarna letters and the Epic of Gilgamesh. It can be used for the alphabetic u, instead of the more common 2nd u, (ú). It has two other uses, commonly. It can be used for the number 10 (especially the Amarna letters from Tushratta of Mitanni, or Burna-Buriash II the king of Babylon), but its probable greater use is for the conjunction, u, with any of the conjunction meanings: and, but, else, etc.

Of the three u's, by graphemic analysis (Buccellati, 1979), the commonness is as follows:

Ù (cuneiform), conjunction only (but also rare, for alphabetic "u")

ú (cuneiform), alphabetic 'u'

u (cuneiform), alphabetic (minor), 10, conjunction (highest use)

Both Ù (cuneiform) and ú are in the top 25 most used signs, but E (cuneiform) and "u (cuneiform)" are not; other vowels (or combination) in the 25 are: a (cuneiform), i (cuneiform), and ia (cuneiform), (which has a secondary use as suffix, "-mine", or "my", thus in top 25 most used signs). Suffix "iYa" is used in the Middle EastSouthwest Asia at present day to end placenames, or other names: "My Xxxxx".
