irb(main):002:0> cmd /c dir /b
=> "folder1\nfolder2\n"
irb(main):003:0> cmd /u /c dir /b
=> "f\x00o\x00l\x00d\x00e\x00r\x001\x00\n\x00\n\x00f\x00o\x00l\x00d\x00e\x00r\x002\x00\n\x00\n\x00"

Notice the '\n\x00\n\x00' sequence for the second call. Expected values are '\n\x00' or '\r\x00\n\x00'.

Even default external encoding is not respected if you'd like to argue about:

irb(main):008:0> Encoding.default_external
=> #Encoding:CP852
irb(main):009:0> Encoding.default_external = Encoding.find 'utf-16le'
=> #Encoding:UTF-16LE
irb(main):010:0> Encoding.default_external
=> #Encoding:UTF-16LE
irb(main):011:0> cmd /u /c dir /b.encoding
=> #Encoding:UTF-16LE
irb(main):012:0> cmd /u /c dir /b
=> "f\x00o\x00l\x00d\x00e\x00r\x001\x00\n\x00\n\x00f\x00o\x00l\x00d\x00e\x00r\x002\x00\n\x00\n\x00"

There is no way to designate external encoding with backqoutes.
Use IO.popen instead.
