Subject: [ruby-core:115422] [Ruby master Bug#20009] Marshal.load raises exception when load dumped class include non-ASCII

Issue #20009 has been reported by ippachi (Kazuya Hatanaka).



----------------------------------------

Bug #20009: Marshal.load raises exception when load dumped class include non-ASCII

https://bugs.ruby-lang.org/issues/20009



* Author: ippachi (Kazuya Hatanaka)

* Status: Open

* Priority: Normal

* ruby -v: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [arm64-darwin22]

* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN

----------------------------------------

## Reproduction code



```ruby

class C���������; end

Marshal.load(Marshal.dump(C���������))

```



## Actual result



```

<internal:marshal>:34:in `load': undefined class/module C\xE3\x82\xAF\xE3\x83\xA9\xE3\x82\xB9 (ArgumentError)

        from marshal.rb:2:in `<main>'

```



## Expected result

Returns `C���������`



## Impacted area

An exception is raised in Rails under the following conditions



* minitest is used with default settings

* Parallel execution with parallelize

* test class names contain non-ASCII characters



The default parallelization uses DRb, and Marshal is used inside DRb.



## Other

After trying various things, I thought I could fix it by making `rb_path_to_class` support strings containing non-ASCII characters, but I couldn't find anything more than that.
