https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64862 --- Comment #8 from Tom Tromey --- Sorry about the extreme delay on this. I think my patch has long since bit-rotted, but I can attach it for reference. I believe my assignment situation got sorted out so this should be fine to read and/or copy from.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64862 --- Comment #5 from Tom Tromey tromey at gcc dot gnu.org --- I have a patch for this. I think it fixes bug 38308 and bug 20110 as well. It works by adding a new function to libcpp to convert a string back to the source charset. I still have to get a new copyright assignment. And the test cases are being a pain to update.

--- Comment #2 from Tom Tromey tromey at gcc dot gnu.org ---
Naturally my example was wrong.
Sorry about that. But gcc still doesn't handle it:
#include stdarg.h
#include uchar.h
extern void p (const char16_t *fmt, ...)
__attribute__((format (__printf__, 1, 2)));
void f()
{
p (u%s %d, 23, hi);
}
... with gcc saying:
r.cc:5:44: error: format string argument is not a string type
__attribute__((format (__printf__, 1, 2)));
^

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64862 --- Comment #4 from joseph at codesourcery dot com joseph at codesourcery dot com --- Note also that gcc.dg/format tests are run both with and without -DWIDE - the intent there is that wide string formats should be tested, when supported, with essentially the same tests as narrow string formats (via appropriate macros to make the tests generic, e.g. wrapping format strings in a macro L()). That could be applied to other string types as well by running the tests more than twice.
