Thank you for your bug report.

You have html entities in your filename. Html entities are not automatically decoded when used in filenames.

sjoerd> Thats bugsweb causing that on unicode characters, first they are converted to entities and then the & is escaped into &. So it ends up with &#XXXX; =)

It seems to me that this is not a bug, but rather a character 
encoding resp. locale related issue.  As the documentation of 
dirname()[1] states:

| dirname() is locale aware, so for it to see the correct 
| directory name with multibyte character paths, the matching 
| locale must be set using the setlocale() function.

FWIW: Assuming UTF-8, the test script could be written:

  $file = "D:\\Backup\\\xE6\x88\x91\xE7\x9A\x84\xE6\x96\x87"
    . "\xE6\xA1\xA3\\\xE7\xBD\x91\xE7\xAB\x99\xE6\xA0\xB9"
    . "\xE7\x9B\xAE\xE5\xBD\x95\cms";
  echo dirname($file);
