If you look up the ascii values of the characters you're looking for, you can make an array of those values and then cast it to char
Example:
d1 = 1:33;
d1 = char(d1);

1:33 was just an example. You'll need to look up the actual ascii character values online. I would suggest a google search for "ascii table". I think most of the characters in the 1:33 range are special characters, not symbols. Try the range 33:47 for a few of the printable characters.

char([33:47, 58:64, 91:96, 123:126])
after that one gets into the non-ASCII characters such as '©'.
Another way of expressing this is:
d1 = union(union(a1, b1), c1);
d2 = setdiff(' '+1:127, d1);
Note: earlier I had setintersect() instead of setdiff()
