GNOME Terminal 3.33.3 (VTE 0.57.3) implements BiDi support, according to
the proposal at https://terminal-wg.pages.freedesktop.org/bidi/ .
In alignment with Diego's comments and my responses to them, it
implements multiple modes. Shuffling the characters according to the
BiDi algorithm is enabled
A few other issues:
In implicit BiDi mode, how should BiDi control characters
(LRE/RLE/LRO/RLO/PDF; LRM/RLM) be handled? We need to remember them.
Which cell should they belong to? How to later override the displayed
string to remove any of these, or insert new ones?
In explicit BiDi mode,
Re Diego:
You are basically right. I'd like to add a couple of points.
As for complex apps such as mc, your approach (2) cannot work. This is
because the BiDi algorithm would not just need to shuffle around
characters that are visible in the terminal; it might need to pull
offscreen chars
Um; It would, as we know, mostly ignore RTL reading users.
now RTL works in kde/konsole beautifully, with shaping and everything,
so I'm not sure how problems mentioned in #46 are handeled there, and
I'm sure its not perfect either, but works better than BiCon for example
but if softwares have
Usama,
The reason for bug #1537064 is me nagging Yaron. The problem of BiDi
cannot be solved in a terminal vt100 environment. The reason - is that
the application does not telling the VTE the boundaries of the
paragraph.
Imagine "mc" opeenning a dialog to rename a file. Lets check the
options;
So enforcing LC_MESSAGES=C or en_US.UTF-8 as a global override will
ignore this issue completely.

If it works as a libvte replacement (and reasonably stable) then I think it
should be default in RTL environments.
However, IMO removal of libvte upon installation is not required. I think both

available with a lower

Should this be considered as default setup in RTL environments?
Why not replace original libvte altogether?

no this is not about Mlterm as long as VTE does not support RTL.
at least there should be a warning or suggestion or message inside the
terminal stating that gnome-terminal does not support RTL and you should
install something else, like Mlterm. that is only when a user installs
RTL language
this is about mlterm? we have a MIR bug 603022 pending for that. can we
either invalidate this or the other bug and use the proper package?

Changing LANG in the terminal will do nothing about Arabic rendering, it

No, we don't have to open a bug for each app that uses vte but the solution
with the 'C' locale does not apply to dpkg since you shouldn't launch any apps
from there...
There are rare situations when apps launch graphical screens, very rare...
So the solution for the dpkg app is relatively
I see where you are going but I can't understand why have you marked the
