Issue #20801 has been reported by mame (Yusuke Endoh).

Bug #20801: Handling non-ascii drive letter on Windows
https://bugs.ruby-lang.org/issues/20801

----------------------------------------
On Windows, non-ascii drive letters are allowed for virtual drives. Some Ruby methods do not seem to handle this well.

```
subst ä: C:\tmp\
```

```ruby
File.absolute_path?("ä:/")      #=> expected: true, actual: false

File.write("ä:/foo.txt", "foo")

Dir.glob("c:/tmp/*.txt")        #=> ["c:/tmp/foo.txt"]
Dir.glob("ä:/*.txt")            #=> expected: ["ä:/foo.txt"], actual: []

Dir.entries("ä:/")              #=> [".", "..", "foo.txt"]
```

It would be nice if someone more familiar with Windows could do a more comprehensive investigation and write a patch.
