+description = """I was trying to execute QEMU with VM from command line(shell) and work inside a VM within that initial console. All goes well except... pasting from clipboard. Pastings from clipboard are truncated to somewhat less (no more) then a terminal width (in columns).
+
+I understand that it seems to be far from QEMU but I tried different terminals/shells/guest systems with the same result. The only things remain the same - QEMU."""
+reproduce = """In Windows open a console (shell). Run QEMU with guest serial attached to QEMU stdio. Try to paste some text. Pasted text will be truncated to 15-35 characters. Before QEMU run and after QEMU exit text pasted normally."""
+additional = """-  Shell probed: **cmd**, **powershell**
+- Terminals probed: **Windows Terminal**, **Alacritty**, **Wezterm**, **Windows Terminal Preview**
+- Guest probed: **Alpine Linux**, **FreeBSD**
+- Setting inside guest probed: various terminal speed/options via **stty**
+- QEMU arguments probed: from **-nographics** to manually define **-chardev/-serial** with/without **-mon**.
+
+Finally I gave up. But want to mention that there are may be bug in source. When I tried to study source to find a hint for my issue I found that (char-win-stdio.c, line 162):
+```
+is_console = GetConsoleMode(stdio->hStdIn, &dwMode) != 0;
+    stdio->dwOldMode = dwMode;
+
+    if (is_console) {
+```
+
+Documentation of **GetConsoleMode** function says:
+```
+Return value:
+
+If the function succeeds, the return value is nonzero.
+If the function fails, the return value is zero.
+```
+
+If understand correctly **is_console** will always be _true_. It will be _false_ only in case of invalid **stdio->hStdIn**.
+
+I don't how this is related to my issue just put here all info I have in hope of resolving."""
