Dear Maintainer,
This came up due to a posting on debian-user-german [1]. Apparently
certain Unicode characters, at least LEFT-TO-RIGHT EMBEDDING [2] and
RIGHT-TO-LEFT EMBEDDING [3] do not trigger the escape code display for
ls with the -b option.
An example script is attached, output:
$ bash unicode_bidir_test.sh
+ touch LTR
+ touch RTL
+ /bin/ls -l
total 4
-rw-r--r--. 1 peter peter 0 Aug 10 14:00 LTR
-rw-r--r--. 1 peter peter 0 Aug 10 14:00 RTL
-rw-r--r--. 1 peter peter 148 Aug 10 14:00 unicode_bidir_test.sh
+ /bin/ls -lb
total 4
-rw-r--r--. 1 peter peter 0 Aug 10 14:00 LTR
-rw-r--r--. 1 peter peter 0 Aug 10 14:00 RTL
-rw-r--r--. 1 peter peter 148 Aug 10 14:00 unicode_bidir_test.sh
+ /bin/ls -lb LTR
/bin/ls: cannot access LTR: No such file or directory
+ /bin/ls -lb LTR
-rw-r--r--. 1 peter peter 0 Aug 10 14:00 LTR
+ /bin/ls -lb RTL
/bin/ls: cannot access RTL: No such file or directory
+ /bin/ls -lb RTL
-rw-r--r--. 1 peter peter 0 Aug 10 14:00 RTL
The expected output would be that those characters be shown, as they are
relevant when accessing a file on the command line.
