Research direction

Start by reproducing the issue in PowerShell 7.1.4 with PSReadLine 2.1.0 in Windows Terminal, using the Cyrillic keymap and CTRL+С. Trace the input and key handling path to determine why the Cyrillic character leaves CTRL+A and CTRL+C unusable. Done means the reported key combinations continue to work in both keymaps and the additional reproduction cases are understood.
