          	return 0;
          }
          
          // Converts 1/2, 1/4, 3/4
          static size_t
          smartypants_cb__number(struct buf *ob, struct smartypants_data *smrt, uint8_t previous_char, const uint8_t *text, size_t size)
          {
          	if (fraction_boundary(previous_char) && size >= 3) {
          		if (text[0] == '1' && text[1] == '/' && text[2] == '2') {
          			if (size == 3 || fraction_boundary(text[3])) {
          				BUFPUTSL(ob, "&frac12;");
          				return 2;
          			}
          		}
          
          		if (text[0] == '1' && text[1] == '/' && text[2] == '4') {
          			if (size == 3 || fraction_boundary(text[3]) ||
          				(size >= 5 && tolower(text[3]) == 't' && tolower(text[4]) == 'h')) {
          				BUFPUTSL(ob, "&frac14;");
          				return 2;
          			}

In particular word boundary is defined as: isspace(c) || ispunct(c); , ispunct includes /
