(input-method bn national-jatiya (version "1.0.0"))
(description "Bengali input method for National Jatiya layout.
https://en.wikipedia.org/wiki/Bengali_input_methods#Bangla_Jatiyo
Layout taken from
https://github.com/OpenBangla/OpenBangla-Keyboard/blob/master/data/National_Jatiya.json
and ported to m17n-db, merging in differences /usr/share/X11/xkb/symbols/bd as far
as possible, giving priority to National_Jatiya.json in case of a conflict.
One of the conflicts is that National_Jatiya.json has ZWNJ on ` and
AltGr+` and ZWJ on ~ and AltGr+~ whereas /usr/share/X11/xkb/symbols/bd
produces the ASCII characters ` and ~ on these keys.
See also:
https://en.wikipedia.org/wiki/Bengali_input_methods#/media/File:KB-Bengali-Jatiyo.svg
The layout picture from Wikipedia shows a few characters on AltGr which do exist
neither in National_Jatiya.json nor /usr/share/X11/xkb/symbols/bd.
On top of implementing the plain “National Jatiya” keyboard
layout, this input method also does “automatic vowel forming”,
i.e. if a diacritical form of a vowel like
া U+09BE BENGALI VOWEL SIGN AA
is typed after a consonant, it is inserted like that but if it is typed
anywhere else, not following a consonant, it is inserted as
আ U+0986 BENGALI LETTER AA
