Actually it seems the issue is that i is missing from the range [a-z]
ı and ğ are missing as well, as are non-Turkish letters like ä that
are included when using the en_US.utf8 locale, even though they are no
English letters either.

(use-modules (ice-9 regex))
(regexp-exec (make-regexp "^([a-z]+)$")
             "iyiyim")

fails.

But running a glibc C program

florian@florianmacbook ~$ cat iyiyim.c
#include <regex.h>
#include <stdio.h>
#define STR "iyiyim"
int main (int    argc,
          char** argv)
{
  regex_t only_letters;
  int r = regcomp (&only_letters, "[a-z]", 0);
  if (r != 0)
    printf ("This error does not happen.\n");
  r = regexec (&only_letters, STR, 0, NULL, 0);
  if (r == 0)
    printf ("The string " STR " matched!\n");
  else
    printf ("No match for " STR ".\n");
}
florian@florianmacbook ~$ gcc -o iyiyim iyiyim.c 
florian@florianmacbook ~$ LANG=tr_TR.utf8 ./iyiyim 
The string iyiyim matched!

succeeds on tr_TR.utf8 and en_US.utf8 locales (and a native Turkish
speaker confirmed to me ıi should be in the alphabet right after h).
Maybe this is a bug in Guile, somehow?

I checked; the graphical installer appears unaffected, but the issue
appears on the installed system.
