Isn't the 'problem' that you are reading the rawunix headers
which don't honour the mime character set encoding, and then
processing them with sed which assumes its input is utf8?

There are many solutions to this, most are ugly (use ape's sed)
or a load of work (upas/fs to support a cookedunix file).
My prefered solution is to replace sed with a trivial c prog
in pipeto.lib:

/*
 * upas/padfrom - prevent upas/fs from miss interpreting
 * the work From in email messages
 */
#include <u.h>
#include <libc.h>
#include <bio.h>

main()
{
	char *p;
	Biobuf bi, bo;

	Binit(&bi, 0, OREAD);
	Binit(&bo, 1, OWRITE);

	while ((p = Brdline(&bi, '\n')) != nil && Blinelen(&bi) > 1)
		Bwrite(&bo, p, Blinelen(&bi));
	while ((p = Brdline(&bi, '\n')) != nil){
		if (strncmp(p, "From ", 5) == 0)
			Bputc(&bo, ' ');
		Bwrite(&bo, p, Blinelen(&bi));
	}
}
