In Unicode, the Sumero-Akkadian Cuneiform script is covered in three blocks in the Supplementary Multilingual Plane (SMP): U+12000–U+123FF Cuneiform U+12400–U+1247F Cuneiform Numbers and Punctuation U+12480–U+1254F Early Dynastic Cuneiform The sample glyphs in the chart file published by the Unicode Consortium show the characters in their Classical Sumerian form (Early Dynastic period, mid 3rd millennium BC). The characters as written during the 2nd and 1st millennia BC, during which the vast majority of cuneiform texts were written, are considered font variants of the same characters. Wikipedia
