[BRLTTY] Russian braille tables and orca issue

[Vsevolod Popov]

Hello.
Recently I started coming across the next issue.
When using Russian computer braille table provided by LibLouis with 
orca, punctuation symbols aren't changed to the symbols described in 
that table.
I can check that by launching the same table in NVDA for Windows.
For example:
The period "." symbol is stated as dot 3 in LibLouis computer braille 
table, but Orca displays it as a literature braille period with dots 256.
After trying to switch braille tables from ru brltty to Ru-compbrl 
LibLouis, I noticed that nothing changes. It seems like the table is 
never changed.
More than that, for some reason Orca stopped changing to any table I 
switch to, for example for English or Spanish braille. When I switch to 
them, orca still continues working with russian brltty table where old 
punctuation rules are applied.
Unfortunately, as I understand nothing could be done in terms of Orca 
development to fix that now.
When I installed Arch, this problem didn't appear, however it appeared 
in Ubuntu before and now it also appears in Arch after several upgrades 
of orca master.
I use Orca master and BRLTTY 6.4.
Is there any possibility to fix that in terms of brltty maybe?
Here is the orca debug.out log if it can help.
