libcpp uses:

#define DSC(str) (const unsigned char *)str, sizeof str - 1

Sometimes this is a bit obscure but it has the nice quality that you
can use the string constant in the place where it is needed, and you
only have to write it once.  (The 'unsigned' is because libcpp uses
unsigned chars everywhere -- gdb wouldn't need this.)

FWIW count-lines-region displays the number of characters as well as
the number of lines.
