I came across something similar when I was writing my matrix display
software and used the following workaround:-
This is part of a character map for a 5x7 dot matrix LED driver
<snip>
__code unsigned char table[128][7] = {
{0x01,0x01,0x01,0x0b,0x0f,0x1f,0x1f}, /* 00h Left fire */
{0x00,0x10,0x10,0x1a,0x1a,0x1e,0x1f}, /* 01h Right fire */
{0x00,0x00,0x1b,0x00,0x04,0x11,0x0e}, /* 02h Smiley1 */
{0x00,0x00,0x0a,0x00,0x04,0x11,0x0e}, /* 03h Smiley2 */
{0x11,0x0a,0x04,0x00,0x11,0x0a,0x04}, /* 04h Chevron down */
{0x04,0x0a,0x11,0x00,0x04,0x0a,0x11}, /* 05h Chevron up */
.
.
.
{0x04,0x04,0x04,0x04,0x04,0x04,0x04}, /* 7ch '|' */
{0x08,0x04,0x04,0x02,0x04,0x04,0x08}, /* 7dh '}' */
{0x0a,0x15,0x00,0x00,0x00,0x00,0x00}, /* 7eh '~' */
{0x00,0x00,0x00,0x00,0x00,0x00,0x00}, /* 7fh '<del>' */
};
main()
{
etc...
Basically you can define static arrays but they have to be declared before
they are used and you have to be explicit that they are stored in the code
segment, in this case it just makes my code a bit more unreadable as there
is now 130 or so lines of code before main(). There may be better ways to do
this but this worked for me :-).
I am sure that you can do similar for your strings.

It looks to be unable to support this (yet):

and needs something like this to change the assignment from compile
time to run time as the assert suggested. You probably will neet to add
#include <string.h>
to pick up the strcpy() prototype as well.

strcpy(demo1,"+--------------+");
strcpy(demo2,"| Ceng 336 |");
strcpy(demo3,"| SDCC LCD demo|");
strcpy(demo4,"+--------------+");
