In debian packaged emacs 25.1.1, starting "emacs -Q /tmp/foo.ses"
" Ret # create a cell with a string
hello Ret # the string content
C-p # move point to that cell
c # ses-recalculate-cell
=>
Format specifier doesn't match argument type: A1
I expected recalc on a string cell to leave it unchanged.
The message looks like a caught error, but I don't know if it's
something bad or merely unsightly. The same happens in emacs 24.
Occasionally I've had c on a string cell clear it to nil. I'll see if I
can make something reproducable for that, if it could be related.

I had a peek at ses.el (a package I don't use regularly), and something
like the following fixes the problem, but is probably totally the wrong
solution.
I've Cc'd the maintainer on this -- Vincent?

Hello Lars,
The root cause is that the default printer is "%.7g". This printer
being a string it is equivalent for (lambda (x) (format xxxx x)),
where xxxx is the concerned string, ie "%.7g".
That default printer comes from the const ses-initial-file-contents,
which hard wires the default printer to "%.7g".
So you can just change your spreadsheet not to get the error by
setting "%s" as a printer to cell A1 (just press p, then "%s", and
then RET). You can also change the default column printer with M-p, or
the default spreadsheet printer with C-c C-p.
A better fix would certainly to accept a new printer format that
instead of a string would be some sort of expression structure that
would map a format string to some predicate, where the predicates
could only be one of stringp , numberp. It could be something
'(printers (stringp . "%s") (numberp . "%.7g"))
So the code would check it for being safe (not to allow viruses on
load) this way
(mapc (lambda (x) (or (and (memq (car x) '(stringp numberp)) (stringp
(cdr x)) (errror "Unsafe printer %S" x))
yyyy)
where yyyy would be the desired value '(printers (stringp . "%s")
(numberp . "%.7g")).
Well, probably what sort of structure we want to accommodate needs
some more thinking.
Vincent.
PS : I cannot make the fix straight away, my personal PC ethernet card
has been broken by the latest storm overvoltage, and the other PC
having my credentials is also under repair after overheating damaged
the connectors (well, nothing surprising as this was a MACbook pro, a
notable unreliable sort of machine wrt to thermal extreme conditions).

Or we could have some extended format string, like this:
"%?n{%.7g%}%?s{%s%}%?*{%S%}"
where whatever is between %?xxxx{ and %} is conditioned by some
predicate xxxx that can be n for numberp, s for stringp, and * for
"none of those at the same level", and some parser would compile this
format string into
(cond
((numberp x) (format "%.7g" x))

Hm... or it could just be an alist like
((numberp "%.7g")
(stringp "%s")
(t "%S"))

After some thought the extended format string seems better to me, it
could be some separate package as that sort of need is not SES
specific, and SES would check if the package is installed or not and
use extended format strings if the package is installed.
That would be a parameter in the sheet whether is uses extended format
strings. So when you share a sheet using extended format with somebody
else that do not have a extended formats, they would receive some
warning that they need to install the package.

I'm not sure I see the logic here -- it's surely a plain and simple bug
stat ses signals an error when you're "recalculating" an ascii value.
Is your concern that fixing this bug will lead to people creating more
spreadsheets with ascii values, and then other people (using older
versions of Emacs) won't be able to use those spreadsheets?
If so, I think that sounds like an unlikely occurrence. And if it does
happen, then there's nothing new about spreadsheets changing the formats
in non-backwards-compatible manner -- the recipient will just have to
update their spreadsheet software, too.
