Subject: [ruby-core:98938] [Ruby master Feature#16985] Improve `pp` for	`Hash` and `String`

Issue #16985 has been reported by marcandre (Marc-Andre Lafortune).

----------------------------------------
Feature #16985: Improve `pp` for `Hash` and `String`
https://bugs.ruby-lang.org/issues/16985

* Author: marcandre (Marc-Andre Lafortune)
* Status: Open
* Priority: Normal
* Assignee: akr (Akira Tanaka)
----------------------------------------
Could we improve `pp` for `Hash` and `String`:

```ruby
pp({hello: 'My name is "Marc-Andr�"'})
# =>
{hello: 'My name is "Marc-Andr�"} 
# instead of
{:hello=>"My name is \"Marc-Andr�\""}
```

If any key is non-symbol, they would continue to be output as `<key> => <value>`. If a string contains single quotes, or characters that need escaping (e.g. `"\n"`), current format would be used.

I'll gladly provide a PR if this is deemed acceptable.

I would even like this for `String#inspect` and `Hash#inspect` but it's not clear if this could lead to much incompatibility (maybe test suites?)
