Additional information about BiCon's behavior
=============================================
BiCon behaves differently if called as "bicon" or "bicon.bin", and also
started from the console (or a tty) versus in a graphical environment.
BiCon ships two keymaps: arabic.map.gz and ir.map.gz and some console
fonts, mainly bicon-8x16-512.psfu.gz.
It can be started as "bicon" or "bicon.bin"
If started as "bicon" it sets the keymap or keyboard layout in a way that
depends whether the "bicon" command is given or not an argument.
1) If started as "bicon" from the console.
If a two character country code is given as argument it is considered
to choose the keymap, else the country (or "territory" to be accurate)
part of LANG is used.
- If the country (converted to lowercase letters) is found in this list:
ae dz eg iq jo ko kw lb ly ma om qa sa sd sy tn ye
then the keymap "arabic" is chosen.
- If the country is "IR" or "ir" then the keymap "ir" is chosen.
The font bicon-8x16-512 is always used with its Unicode map.
IMPORTANT. You won't be able to use the "setfont" command after having
started bicon as a regular user. You will have to temporarily become root
with "su" to change the font if you want.
2) If started as "bicon" from an X terminal.
You will need to use an UTF-8 capable or enabled terminal.
A switchable keyboard layout (US + the language that corresponds to the
country set by the user or found in LANG) is set.
IMPORTANT:
- BiCon doesn't set the font. You'll have to do that yourself. Be careful
to use a font including the needed glyphs.
- BiCon sets the "option" for the X server to:
"grp:alt_shift_toggle,grp_led:scroll"
and the "layout" to:
"us,<ir or (country code)>"
This will override the key combination that you possibly have set in
/etc/X11/xorg.conf.d/90-keyboard-layout.conf to toggle keyboards.
But you can change the settings made by BiCon with a command like this
one (after having started BiCon, of course):
setxkbmap \
-display "$DISPLAY" \
-layout "<layout1>,<layout2>" \
-option "<your options"> \
-print | \
xkbcomp -w 2 - "$DISPLAY"
3) If started as bicon.bin, BiCon doesn't load any font or keymap.
You might prefer it that way if you want to keep your own settings.
Reference: file bin/bicon.in in the source archive.
