If I'm editing a tar file, and I change a subfile's owner or group, I
get the following:
Debugger entered--Lisp error: (cl-assertion-failed (not (or enable-multibyte-cha
racters (multibyte-string-p new-data-string))))
signal(cl-assertion-failed ((not (or enable-multibyte-characters ...))))
tar-alter-one-field(265 "root tar-chown-entry("root")
call-interactively(tar-chown-entry nil nil)
and tar will be unable to read that particular tar header. I'm
able to work around it with the following advice:
(defadvice tar-alter-one-field (around fix-multibyte-input)
(let ((new-data-string (ad-get-arg 1)))
(if (multibyte-string-p new-data-string)
(ad-set-arg 1 (string-to-unibyte new-data-string)))
ad-do-it))
This is on a Debian 4.0 box with GNU tar 1.16.
