ObC (What did I mess up here?):

Answer (I think?): the %x printf conversion expects an unsigned int.

$ cat readit.c
#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>
#include <string.h>

int main(void)
{
DIR * this = {0};
struct dirent * entry = {0};
char * s;
int dc = 0; // display character

this = opendir(".");
while ((entry = readdir(this))!=NULL)
    {
    if(!strcmp(entry->d_name,".")) continue;
    if(!strcmp(entry->d_name,"..")) continue;
    for(s = entry->d_name; *s ; s++)
        {

        dc = (*s<0) ? 256+*s : *s;
           
        printf("%x\n",dc);

        }
    puts("---");
    }

return 0;
