Hi, There are some issues with the stretched x that has been accepted from N4081 (Revised proposal to encode “Teuthonista” phonetic characters in the UCS) and N4106 (Teuthonista ad hoc report) and the proposed Latin chi from N4262 (Proposal to encode “Unifon” and other characters in the UCS). According to Michael Everson stretch x and Latin chi are different strictly speaking, because of their shape and difference in weight of diagonals – stretched x has the \ diagonal thicker than the / diagonal, while the API Latin chi has the / diagonal thicker than the \ diagonal (like Greek chi). Although this is true. I don't believe these are clearly different glyphs, I seriously doubt this makes them different characters or that there is any evidence supporting such difference.
1. The two stretched x used in Sprachatlas von Bayerisch-Swaben (SBS) and Sprachatlas von Unterfranken (SMF) which are not the same glyphs strictly speaking represent the same sound represented with chi (Greek glyph) in other works using Teuthonista. 1.1 The stretched x used in those example are either in italic form (SBS), which is identical to Lepsius's chi, or in sans serif form (SMF), which is no different than some sans serif Greek chi except that it is taller than x-height instead of below the baseline. 1.2 The stretched x used in Gabriel 1985 Einführung in den Vorarlberger Sprachatlas (VALTS) is actually the glyph of Greek chi. 2. The capital Latin chi proposed in N4262 is actually based on evidence of Lepsius's chi which has a different shape strictly speaking than the one proposed. In other words, the proposed glyph has no evidence of use. Since those glyphs represents the same sounds (within works using Teuthonista) or very similar sounds, and never co-occur should they not be unified? Lepsius Roman and italic Chi.png from Zeitschrift für ägyptische Sprache und Altertumskunde (1868) http://www.archive.org/stream/zeitschriftfr06brug#page/94/mode/1up -- Lepsius' roman and italic capital chi are not the same as proposed capital Teuthonista 1965-Wiesinger.jpg from Teuthonista 1965 -- Teuthonista's chi is using Greek chi's glyph N4081 - König 1997 - stretched x.png from SBS -- italic stretched x, almost identical to Lepsius italic chi. N4081 - Gabriel 1985 - stretched x.png from Einführung in den Vorarlberger Sprachatlas -- this example of stretched x (letter and modifier letter) in N4081 is the same glyph as Greek chi. N4081 - SMF 2.2 - stretch x from SMF 2.2 -- this example of stretched x in N4081 is taller than x-height but similar to Greek chi in some sans serif fonts. N4262 - comparison with unseen Latin capital chi.png -- This comparison in N4262 gives Latin letter capital x, Latin letter small x, Latin letter small stretched x ~ Greek letter capital chi, Greek letter small chi ~ proposed Latin letter capital chi, proposed Latin letter small chi. However the Roman examples of stretched x in N4081 are taller than x-height and not below baseline, the Italic examples are like Greek chi or like Lepsius's chi. Furthermore, the proposed Latin letter capital chi has no actual examples (stricly speaking with glyph -- only Lepsius' capital chi has been used instead). -- Denis Moyogo Jacquerye
