Agree that bidi chars is the way it SHOULD be done, however in current
state of affairs, there's two problems with these:
1) There's no general way of typing them. Some apps might have them, but
it really should be done by an xkb keyboard layout (the standard hebrew
one does not include bidi stuff).
For that specific issue - I've prepared an xkb symbols file. It's
included in the attached bash-script, which acts as an
installer/uninstaller/activate/deactivate tool (just put it in
/usr/local/bin and your'e fine).
To access the new keys: *in hebrew mode only* press
SHIFT+F{1,2,3,4,5,6,7} (instructions are also printed by the installer.
Pls let me know of any comments or suggestions (esp: which keys you
think they should be on).
2) Applications don't always handle them right. For example, OpenOffice
handles them correctly, but makes them visible - depending on the font,
you usually see an annoying blank square in their place (they should be
invisible - at least if you call yourself WYSIWIG). gedit behaves quite
well with these chars - but there's some annoying issues concerning
cursor movement with arrow keys.
