Bug #17626: FileUtils.cp may cause utime_failed

----------------------------------------
FileUtils.cp will cause utime_failed if the file name contains Japanese characters and preserve is true.

This will probably only happen on Windows. It occures on Windows 10 version2004 build 21301.1010.

``` ruby
require 'fileutils'

FileUtils.cp('foo', 'foo_copy', preserve: true)
FileUtils.cp('foo', 'fooコピー', preserve: true)
```

``` sh
$ ruby test.rb
C:/tools/ruby30/lib/ruby/3.0.0/fileutils.rb:1424:in `utime': No such file or directory @ utime_failed - fooコピー (Errno::ENOENT)
        from C:/tools/ruby30/lib/ruby/3.0.0/fileutils.rb:1424:in `copy_metadata'
        from C:/tools/ruby30/lib/ruby/3.0.0/fileutils.rb:515:in `copy_file'
        from C:/tools/ruby30/lib/ruby/3.0.0/fileutils.rb:433:in `block in cp'
        from C:/tools/ruby30/lib/ruby/3.0.0/fileutils.rb:1597:in `block in fu_each_src_dest'
        from C:/tools/ruby30/lib/ruby/3.0.0/fileutils.rb:1613:in `fu_each_src_dest0'
        from C:/tools/ruby30/lib/ruby/3.0.0/fileutils.rb:1595:in `fu_each_src_dest'
        from C:/tools/ruby30/lib/ruby/3.0.0/fileutils.rb:432:in `cp'
        from test.rb:4:in `<main>'
```

The expected result is copy to fooコピー is success same like copy to foo_copy.
