We have had a few bugs with v4 related to file encodings, especially on Windows. Windows uses its own character encodings instead of `utf-8`, often `cp1252`. Some characters cannot be decoded using `utf-8`, causing `UnicodeDecodeError`. There are a couple places where this can cause problems: - In the installer bootstrap, we install or upgrade `pip` and decode the result, using `subprocess`. The input to this includes the user's home dir. In #6105, the user had one of the problematic characters in their username. `subprocess` attempts and fails to decode the username, which crashes the installer. To fix this, we need to use `locale.getpreferredencoding()` when executing the command. - Similarly, in the model install service and config class, we attempt to load a yaml config file. If a problematic character is in the path to the file (which often includes the user's home dir), we can get the same error. One example is #6129 in which the models.yaml migration fails. To fix this, we need to open the file with `locale.getpreferredencoding()`.

Preparations:
You will need to install Python 3.10 or higher for this installer
to work. Instructions are given here:
https://invoke-ai.github.io/InvokeAI/installation/INSTALL_AUTOMATED/
Before you start the installer, please open up your system's command
line window (Terminal or Command) and type the commands:
python --version
If all is well, it will print "Python 3.X.X", where the version number
is at least 3.10.*, and not higher than 3.11.*.
If this works, check the version of the Python package manager, pip:
pip --version
You should get a message that indicates that the pip package
installer was derived from Python 3.10 or 3.11. For example:
"pip 22.0.1 from /usr/bin/pip (python 3.10)"
Long Paths on Windows:
If you are on Windows, you will need to enable Windows Long Paths to
run InvokeAI successfully. If you're not sure what this is, you
almost certainly need to do this.
Simply double-click the "WinLongPathsEnabled.reg" file located in
this directory, and approve the Windows warnings. Note that you will
need to have admin privileges in order to do this.
Launching the installer:
Windows: double-click the 'install.bat' file (while keeping it inside
the InvokeAI-Installer folder).
Linux and Mac: Please open the terminal application and run
'./install.sh' (while keeping it inside the InvokeAI-Installer
folder).
The installer will create a directory of your choice and install the
InvokeAI application within it. This directory contains everything you need to run
invokeai. Once InvokeAI is up and running, you may delete the
InvokeAI-Installer folder at your convenience.
