Fix char panic (#12867)
# Description
The `char` command can panic due to a failed `expect`: `char --integer
...[77 78 79]`

This PR fixes the panic for the `--integer` flag and also the
`--unicode` flag.

# After Submitting
Check other commands and places where similar bugs can occur due to
usages of `Call::positional_nth` and related methods.

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
