Tu (cuneiform) Tu (cuneiform) The cuneiform sign tu, and for TU-(the sumerogram, capital letter (majuscule), in the Hittite language and other cuneiform texts, is a common-use syllabic sign for ""tu"", and also with a syllabic use for ""t"", or ""u"". It is not a multi-use sign, with other alphabetic sub-varieties. The Sumerian language version is similar to the usage in the Amarna letters, with the 3-horizontal strokes connecting the 4-angled wedges on the left, and connected to the vertical horizontal single-stroke, at right. Varieties exist: for example Amarna letter EA 271 shows 4-hortizontal long-strokes, with 2 short-strokes, between the two long ones,
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"
