The alphabets are based on what is used in
"Dictionnaire Général de la Langue Amazighe Informatisé"
by IRCAM (https://tal.ircam.ma/dglai/lexieam.php, DGLAi).
This was also requested by the community in the Tashelhit
Wikipedia Incubator.
Changes:
* Tests are enhanced to cover the whole alphabet.
* The Latin letter š is replaced with the letter c as
the equivalent of Tifinagh letter ⵛ.
* The Tifinagh letters ⵠ and ⵒ are eliminated
because they are not used in the Moroccan version
of Tifinagh, as presented in the DGLAi.
* The Latin letters O, P, V are converted to the
Tifinagh letters ⵓ, ⴱ, ⴼ, which are the same letters
that correspond to the Latin letters U, B, and F.
* Greek Gamma and Epsilon characters are replaced with
the corresponding characters from the Latin range.
* All the non-ASCII Latin letters are added to
the uppercase-lowercase Latin conversion.
This is the first patch in a series to fix the most important
issues listed above. It's kept minimal to make reviewing easier.
There will be more patches to fix readability and public/private
members, and to add more tests.
