Thank you.

No offense meant (!), but you possibly should adjust

      if (mode == STRING_DOWNCASE)
        nc = tolower(c);
        nc = toupper(c);


      if ((unsigned char)c & 0x80) {
        del mac;
        error("cannot apply string case transformation to non-ASCII ('%1')",
      } else if (mode == STRING_DOWNCASE)
        nc = tolower(c);
        nc = toupper(c);

before the release is out and people start creating manual pages
with "normal" casing and these requests become used.
Yes, i wanted to look for (non-standard?!) isascii(3), but like so
is stumbled upon problems (just try "git grep -i isascii master"),
there are quite some

  #ifdef isascii
  #define ISASCII(c) isascii(c)
  #define ISASCII(c) (1)

and that is of course plain wrong, it should be

  #ifdef isascii
  #define ISASCII(c) isascii(c)
  #define ISASCII(c) (((unsigned char)c & 0x80) == 0)
