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()`. |
