    Thanks. Just wanted to make sure it wasn't set to an unexpected value which has caused issues with echoing.

    Keith Hill (@rkeithhill), this problem is probably caused by PowerShell, because using file://localhost/data/data/com.termux.nix/files/home/.nix-profile/bin/pwsh 1 via f-droid.org/repo/com.termux_118.apk 2 causes the same problem.

    You could disable echo with stty -echo (before or/and inside flatpak).
    Also you could remove RSReadline for test.

    Ilya (@iSazonov), although Remove-Module PSReadLine (undesirably) removes text colouration, it, like stty -echo, does remediate this, inside /data/data/com.termux.nix/files/usr/nix/store/nx317a2z1yhp7a9vs337jfnbnniphcbj-powershell-7.4.2/share/powershell/pwsh, inside ../../../gfzfsn0pwbzgj188n21d5r04z80hbswc-bash-interactive-5.2p32/bin/bash: 1

    …nor flatpak-spawn:

    My apologies if I've not executed those commands correctly.

    I guess flatpak hides real terminal and C# application thinks it work with file/stream. You could try flatpak-spawn --host script -q /dev/null -c "pwsh" where script creates real PTY for application.
