The program must print the following block of text of LED numbers exactly.

+-----------------------------------------------------------------+

Notice the 1-char padding inside the borders. The trailing newlines, and the types of the newlines are not significant. However, the whitespaces are the spaces you get when you press spacebars (ASCII 32).

Shortest code wins. Using data encoding (base64, gzip), or compressing with other Unicode characters is discouraged. You cannot use programs like cat or gzip since they are not programming languages.

The character count must be less than 600 to qualify.

    \$\begingroup\$ I always object to problems that have the form "solve this instance of a problem" rather than "write a program to solve any problem in this class". And if we make it general it becomes very similar to Code Golf - Banner Generation. \$\endgroup\$

    \$\begingroup\$ What do you mean by data encoding is discouraged? We can't use an array of encodings, say of a bit mapping of the characters to print from? \$\endgroup\$

Unfortunately some of the characters are control codes, so I'm going to have to post a hexdump and a link rather than a direct copy of the source:

leds.gs

Note that all of the characters are 7-bit values and legal Unicode code points, so the number of characters is the same as the number of bytes in UTF-8.

Basically there are two hard-coded arrays. The first is a 15-element bitmap indicating which of the 7 segments control each grid cell. The second is the 7-segment encoding of the 16 characters. Then it's just a case of using bitwise and to work out which segments are turned on and doing some string manipulation.

Java, 302 characters

class A{public static void main(String[]a){String d="w$]m.k{%o?zS|[#!% \" $ :(L 0 @ p` ",s="";for(int y=0;y<9;y++){s+=y%8==0?"+-":"| ";for(int x=0;x<64;x++)s+=y%8==0?"-":y!=1&&y!=7&&((d.charAt(8+x%4+y*4)-32)&d.charAt(x/4))>0?(char)((x<40?48:55)+x/4):" ";s+=y%8==0?"+\n":"|\n";}System.out.println(s);}}

Expanded :

public class A {
    public static void main(String[] args) {
        String d = "w$]m.k{%o?zS|[#!% \" $ :(L 0 @ p` ", s = "";
        for (int y = 0; y < 9; y++) {
            s += y % 8 == 0 ? "+-" : "| ";
            for (int x = 0; x < 64; x++)
                s += y % 8 == 0 ? "-" : 
                    y != 1 && y != 7 && ((d.charAt(8 + x % 4 + y * 4) - 32) & d.charAt(x / 4)) > 0 ? 
                            (char) ((x < 40 ? 48 : 55) + x / 4) : " ";
            s += y % 8 == 0 ? "+\n" : "|\n";
        }
        System.out.println(s);
    }
}

The digits shapes are encoded in a byte with the following pattern:

  1 1 1
2       4
2       4
2       4
  8 8 8
16      32
16      32
16      32
  646464

e.g number 5 is 1|2|8|32|64 = 107

When outputting the text, each "pixel" (character) is set only if some "lines" of digits are enabled. For example, the upper-left character of a digit is set only if the line 1 or 2 are enabled. The lower-down character is set only if lines 32 or 64 are enabled.
