Unexpected characters appear, when "not found" message is shown in the console.

In trace string looks correct:
find mask: .* (for /home/igor/projects/test/far/far2l/Build/.*) - ..
OnKeyUp: 2e 2e 0 18367836
OnKeyDown: d d 0 18368369

ConsoleInput::Enqueue: 13 13 DOWN

RegSetValue type=4 cbData=4
CommandLine::ShowBackground: done
ExecClassifier('start .') - open error 2
setting console size: 140 x 47
ioctl(TIOCSCTTY): Operation not permitted

I suppose, null-termination is somewhere missing or the length calculated incorrectly. Or there is sometimes completely wrong pointer.

this looks like ANSI escape characters thay should be processed and show funcy colors but somewhy magic didn't happen, there're lot of issues with built-in terminal, its not a easy fix

[elfmz]

is this still actual?

Looks like not any more.
