Re: Possible to add new precomposed characters for local language in Togo?

[Asmus Freytag (t)]

Mats, it is really useful to document (let me amend that to "immensely useful" to document) the required combinations (perhaps in a Unicode Technical Note on African Writing Systems). It may even be useful to ask for these sequences to become "named sequences" to further indicate that they are standard (and not ad-hoc) combinations. However, precomposing these is simply out. Unicode locked that door and threw away the key (short answer). The long answer will come along shortly. Hope this helps.

However many of the languages have several tones and even use combined tones. However when I tried to update the composer to make it work it seems like the composer only can give back a precomposed character and not a string with combined characters. I now wonder, generally, is it best to add new precomposed characters to Unicode? Should there be a unicode symbol for each combination used? What is best practise? I ask because I see some unicodes are precomposed characters, I'm not sure why they are useful, but if they are maybe we also should add these? For reference here are the combinations needed, as you can see there are many! I've tried to check over, I don't think there exists precomposed characters for any of them. ɛ / epsilon = U025B <dead_acute> <U025B>                     : "ɛ́"   LATIN SMALL LETTER EPSILON WITH ACUTE
