from font_6x11.c:

#include <linux/font.h>

#define FONTDATAMAX (11*256)

static const unsigned char fontdata_6x11[FONTDATAMAX] = {

<snip>

	/* 35 0x23 '#' */
	0x00, /* 00000000 */
	0x00, /* 00000000 */
	0x28, /* 00 0 000 */
	0x7c, /* 0     00 */
	0x28, /* 00 0 000 */
	0x28, /* 00 0 000 */
	0x7c, /* 0     00 */
	0x28, /* 00 0 000 */
	0x00, /* 00000000 */
	0x00, /* 00000000 */
	0x00, /* 00000000 */

There is no real format, it's just an array full of bits on or off.

It might be worth it if it can translate from whatever text output
you're starting from to the hexadecimal values you need. I remember I
wrote the comments by hand, then translated that to the hex values I
needed in awk.

Good luck,
