We mapped the available glyphs and accents for the Amis language.
The letters in alphabetical order:
a c d f ng h i k l m n o p r s t u w y
Everyone of them can get an acute or circumflex accent on top. ng can get a dot on top of the g.
The accents are literally on top: i would get the dot PLUS the accent on top.
Not all accented characters directly exist in Unicode; however Unicode developed various kinds of combination features to take care of these cases.
Then we need an input method that would insert ng instead of g and allow to type all the accent combinations.
Here is the full character set:
a á â
c ć ĉ
d d́ d̂
f f́ f̂
ng nǵ nĝ nġ
h h́ ĥ
i i̇́ i̇̂
k ḱ k̂
l ĺ l̂
m ḿ m̂
n ń n̂
o ó ô
p ṕ p̂
r ŕ r̂
s ś ŝ
t t́ t̂
u ú û
w ẃ ŵ
y ý ŷ
Update: this character list has been improved and the good version is found in the Debian wiki.
The list is not displayed correctly with many fonts or rendering engines. Arne made a test page that explicitly sets a font that works.
The accents are not taken into account when sorting.
Uppercase letters are not used.
Note: the page has been updated to reflect further input from Unicode and Amis people.
Update: there is now a wiki page on the Debian wiki.
