Add note on local morphologies of Ɓ rendered as Ƃ in Dan and Kapelle

[clauseggers]

The capital Ɓ has the form of Ƃ in the original document, which is not the current standard form for capital for this letter in most languages but is still preferred for Dan and Kpelle in Liberia.

@clauseggers what "original document" are you referring to and what is the change in Hyperglot that you propose?

[clauseggers]

The origin seems to be ‘Practical Orthography of African Languages
Look at the second table http://www.bisharat.net/Documents/poal30-tables.html#tbl

[moyogo]

Specifically this is the Gio (Dan in Liberia) [dnj] orthography, Liberia Kpelle [xpe] orthography and also Loma [lom] in Liberia. Dan (Eastern Dan and Western Dan) [dnj] in Côte d’Ivoire (same language as Gio in Liberia in ISO 639-3), Guinea Kpelle [gkp], Toma [tod] in Guinea.

The Practical Orthography of African Languages is a general reference and shows the usage of the early 1930s. Liberia languages had their orthographies defined around that period.
However Hausa started using Ɓ with the top-left-hook like Ɗ in the late 1930s. After the 1960s, general reference alphabets used the top-left-hook form of Ɓ and this is likely why most languages that use the letter do so as well since their current orthographies date from after that.
