Branch to save Enhanced video buffer or Legacy video buffer (Unix).

Implementation of Kitty keys and xterm - ModifyOtherKeys (Unix keyboard)

Enable mouse in pterm (putty)

Windows console mouse - scroll up and down events

Additional function key escape sequences for rxvt (urxvt)

In console enable mouse buttons browse back/forward (xterm Unix)

Go32v2 and msdos mouse is zero based. Fixed GetMouseX, GetMouseY and SetMouseXY.

make file gitlab web interface friendly

Silent key apostrophe. Fixed problem for Windows Textmode IDE in Linux under Wine.

Console keyboard shift states in Unix

Multi byte mouse report format for rxvt (Unix)

* fcl-fpterm/fpmake.pp modified, so it includes a function, similar to
rtl-console/fpmake.pp. This is to allow declaring constant sets for the OSes.

RawReadString is limited to length of shortstring, don't read more than that

Correct mouse button mapping under Unix

Escape key press while rapidly move mouse don't print escape sequence on screen

No mouse up events for mouse wheel.

Exposes in interface ConvertToLegacyKeyEvent.

sync with video.pp

Fixed doubling of ESC key events in kitty and legacy modes
Fixed wrong condition (Alt+NonLatin top menu hotkeys now work again)

This commit significantly enhances text input and editing in non-Unicode environments on Unix-like systems. The video unit now automatically detects the appropriate legacy (OEM) codepage based on the LANG environment variable, replacing the previous hardcoded default. This allows applications using Free Vision, like the built-in editor, to correctly display at least the most frequently occurring symbols in various legacy encodings. Furthermore, the keyboard unit now correctly translates Unicode key input into the detected single-byte codepage, enabling proper input of national characters, such as Russian, even in non-Unicode builds.
