Bonjour J-J –

It's not that the pipe modifies the stream, it's that 'ls' has decided that
'e-accent-aigu' is unprintable in the current locale.

Try ls -B and then investigate the locale.

*-B*      Force  printing	of  non-printable  characters  (as  defined by
	       *ctype*(3)
<https://man.freebsd.org/cgi/man.cgi?query=ctype&sektion=3&apropos=0&manpath=FreeBSD+14.0-RELEASE+and+Ports>	and
current locale settings) in	file  names  as	 *\**xxx*,
	       where *xxx* is the	numeric	value of the character in octal.  This
	       option is not defined in	IEEE Std 1003.1-2008 ("POSIX.1").
