Mine is "ls (fileutils) 4.1", and that works correctly even
if the stdout is a pile in any locales as below.

[~/tmp:709] LANG=ja_JP.eucJP \ls -l --dired abc* 123*|cat
  -rw-rw-r--    1 handa    handa           6 Jan 27 13:50 1234567
  -rw-rw-r--    1 handa    handa           6 Jan 27 13:51 abc
def
//DIRED// 58 65 124 131
//DIRED-OPTIONS// --quoting-style=(null)
[~/tmp:710] LANG=de_DE \ls -l --dired abc* 123*|cat
  -rw-rw-r--    1 handa    handa           6 Jan 27 13:50 1234567
  -rw-rw-r--    1 handa    handa           6 Jan 27 13:51 abc
def
//DIRED// 58 65 124 131
//DIRED-OPTIONS// --quoting-style=(null)
[~/tmp:711] LANG=C \ls -l --dired abc* 123*|cat
  -rw-rw-r--    1 handa    handa           6 Jan 27 13:50 1234567
  -rw-rw-r--    1 handa    handa           6 Jan 27 13:51 abc

//DIRED// 58 65 124 131
//DIRED-OPTIONS// --quoting-style=(null)

The difference with your case is in --quoting-style, I don't
know that meaning.
