InscriptBugs

Missing chars in Inscript keymaps

While inscript keyboard layout is implemented in XKB maps, some characters in unicode ranges are missing in many maps. This step is to extend the basic inscript layout to accomodate the missing chars. This way the keymap (which is basic form of input) supports the script completely.

A complete layout of inscript for different languages is available at http://tdil.mit.gov.in/keyoverlay.htm

The list is trying more for completeness, so characters existing for compatibility with other lang/scripts, even if they are not common in use are still listed.

Indic XKB keymaps are in /etc/X11/xkb/symbols/ and /etc/X11/xkb/symbols/pc/

Bengali - ben
Gujarati - guj
Devanagari - dev
Kannada - kan
Malayalam - ml
Oriya - ori
Punjabi - gur
Tamil - tml
Telugu - tel

XKB keymaps (in /etc/X11/xkb/symbols verified from xlibs (4.3.0.dfsg.1-14sarge1) Debian Sarge 3.1r0 , wrt. Unicode v4.1

Xorg packages have all keymaps rolled into one keymap file 'in' with devanagari as default. Updates to be made there and pushed into cvs.

Unicode chars which should be present
zero width joiner

zero width nonjoiner

Invalids are codes found in keymap but dont exist in the unicode range or are reserved slots.
