 I have a sample reproducer. An example is the second line below (as
 output here by "cat -v"), which has an escape sequence trying to
 function as a web link:
 
 xjack.c: In function 'xjack_draw':^M
 xjack.c:350:34: warning: array subscript has type 'char' 
 [^[]8;;https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wchar-subscripts^G-Wchar-subscripts^[]8;;^G]^M
    350 |       if ((tolower(c) != tolower(*st->s))^M
        |                                  ^^M
 
 I've placed the reproducer file at
