I was looking at unicode.c and I've seen code I never seen
before. Is it possible to write such a code?

char *unicode[19][21][28] =
{
{
"°¡",
"°¢",
....
and so on.

I only seen code like a[][] not a[][][]

And how many dimensions are allowed at maximum in standard?

Well, there is no definitive answer because of the way the standard is
worded, but a conforming compiler must accept at least one program with:

"12 pointer, array, and function declarators (in any combinations)
modifying an arithmetic, structure, union, or incomplete type in a
declaration"

so in your case, 11 array declarators can be used.
