Comment 6 for bug 1781706

Hi, thank you all for your contribution, I had similar issue while using:

Ubuntu 20.04.2 LTS (GNU/Linux 5.8.0-43-generic x86_64)
terminator/focal,focal,now 1.91-4ubuntu1 all [installed]

Here is a summary of what I did based on your notes

sudo bash
cd /usr/share/terminator/terminatorlib/plugins
cp custom_commands.py custom_commands.py.bak.$(date +%Y-%m-%d_%H%M)
vi custom_commands.py +130

   Change line 130 of terminatorlib/plugins/custom_commands.py
   from:
   terminal.vte.feed_child(command, len(command))
   to:
   terminal.vte.feed_child(command.encode())

py3clean .
python3 -m compileall .

Then quit all instances of terminator and started again.
