# Description

This PR allows oem code pages to be used in decoding by specifying the
code page number.

I abstracted the decoding a bit. Here are my function comments on
how/why.
```rust
// Since we have two different decoding mechanisms, we allow oem_cp to be
// specified by only a number like `open file | decode 850`. If this decode
// parameter parses as a usize then we assume it was intentional and use oem_cp
// crate. Otherwise, if it doesn't parse as a usize, we assume it was a string
// and use the encoding_rs crate to try and decode it.
```

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.

This crate contains the majority of our commands

We allow ourselves to move some of the commands in nu-command to nu-cmd-* crates as needed.
