Certain signs to indicate names of gods, countries, cities, vessels, birds, trees, etc., are known as determinatives and were the Sumerian signs of the terms in question, added as a guide for the reader. Proper names continued to be usually written in purely "logographic" fashion. The earliest known Sumerian king whose name appears on contemporary cuneiform tablets is Enmebaragesi of Kish. Surviving records only very gradually become less fragmentary and more complete for the following reigns, but by the end of the pre-Sargonic period,
Cuneiform (Unicode block) there are signs written as ligatures of varying constituent signs, such as KURUM (Borger 2003 no. 729) that was written IGI.NÍG in early times, but later IGI.ERIM. Since there is no code point for KURUM, the sign must be expressed as either IGI.NÍG (U+12146 U+1243C, ) or IGI.ERIM (U+12146 U+1209F, ) depending on the shape of the glyph, in violation of the basic principle of Unicode to encode characters, not glyphs. While those signs can in principle still be added by a "Cuneiform Extended" range in the future, as has been done for a number of other scripts ("Latin Extended"
