In the case of ɖ vs ð vs đ, there are three different letters, as follows from their names, that happen to have identical capital glyphs (those you've mentioned plus U+0110 LATIN CAPITAL LETTER D WITH STROKE).
Speaking of đ, "an alternate glyph with the stroke through the bowl is used in Americanist orthographies" without any [loud] cries about disunification. If N-Eng and n-Eng are disunified but small engs aren't (should they?), who keeps the "default" "toupper" conversion? > And while they are at it, I wouldn't refuse if they squared the circle. That's exactly right. Leo On Thu, Dec 12, 2013 at 2:52 PM, Asmus Freytag <asm...@ix.netcom.com> wrote: > On 12/12/2013 2:25 PM, Leo Broukhis wrote: > > Hmmm...
