We mapped the available glyphs and accents for the Paiwan language.
The letters in alphabetical order:
a b c d e f h i j k l m n p q r s t u v w y z ḏ nġ ḻ ṟ ṯ
No uppercase.
Update: this character list has been improved and the good version is found in the Debian wiki.
All the characters are in Unicode except nġ, which already needs to be requested for the Amis script.
We need to design an input method to enter the underlined letters and the nġ.
Update: there is now a wiki page on the Debian wiki.
