Subject: [ruby-core:79279] [Ruby trunk Bug#13162] tr does not recognize multi-byte characters correctly

Issue #13162 has been reported by Tsuyoshi Sawada.

Bug #13162: tr does not recognize multi-byte characters correctly
https://bugs.ruby-lang.org/issues/13162

* Author: Tsuyoshi Sawada
* Status: Open

* Assignee: 
* Target version: 
* ruby -v: 2.3.3
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
This looks as expected:

```
"\\".tr('\\', '���') # => "���"
```

but this doesn't:


```
"\\".tr("\\��'", "������'") # => "\\"
```

I confirmed the strings are UTF-8.
