Yes, I know this but you cannot go from Berber written in Arabic to Tifinagh or Latin Scripts without losing some information. At least, according to some scholars' system. Do you also plan to modify the Arabic script as used by the current user of Berbere before coding the Tifinagh script ? > You seem to forget that Tifinagh is not a unified script, (sigh) > but a set of separate scripts where the same glyphs are used with distinct semantic functions. Phonemic, I suspect. In any case, what is the problem with several characters having the same "representative" glyph in the code chart (they also have a name) ? I believe this is already the case for other characters. Some characters don't even have no glyph representation. > And I think it is the major issue which requires to choose a policy >for its encoding.

Because it is best to use Tifinagh glyphs as representative glyphs of the Tifinagh script? Because the character names also specify the value of characters? And because, even if the script is not unified and some sign are not used everywhere, many signs are. I counted 16 common glyphs between the Hoggar variety and the Acad�mie berb�re's one, out a total of 28 glyphs found in these two varieties. Nine characters use different glyphs in the two varieties and 3 characters exists in Acad�mie berb�re's proposal but have no mapping (even ambiguous ones) in the Hoggar's variety. Only in the case of vowels, where the Hoggar variety which does not distinguish between vowels and semi-vowels (has 2 signs instead of 4), would it be ambiguous to use the Hoggar signs since the Acad�mie Berb�re uses different signs for the semivowels /w/ and /j/. But I agree that chosing the representative glyphs may become a sensitive issue if the Tifinagh script is to be unified, each school might feel offended that its preferred glyphs were not chosen in ISO/IEC 10646. This does not necessarily mean that Tifinagh should be encoded with an easy Latin mapping in mind. P. A.
