Ok, I hate LCD4Bit, here's some code to do it with LiquidCrystal:

#include <LiquidCrystal.h>
LiquidCrystal lcd(2, 3, 4, 5, 6, 7, 8);

byte custchar[8][8] = {
{
B11111,
B11111,
B11111,
B00000,
B00000,
B00000,
B00000,
B00000
}, {
B00000,
B00000,
B00000,
B00000,
B00000,
B11111,
B11111,
B11111
}, {
B11111,
B11111,
B11111,
B00000,
B00000,
B11111,
B11111,
B11111
}, {
B00000,
B00000,
B00000,
B00000,
B00000,
B01110,
B01110,
B01110
}, {
B00000,
B00000,
B00000,
B01110,
B01110,
B01110,
B00000,
B00000
}, {
B00000,
B00000,
B00000,
B00000,
B00000,
B00000,
B00000,
B00000
}, {
B00000,
B00000,
B00000,
B00000,
B00000,
B00000,
B00000,
B00000
}, {
B00000,
B00000,
B00000,
B00000,
B00000,
B00000,
B00000,

};
