Use a graphic LCD instead and you will be able to do much more.

Sorry, I don't. IIRC, you can download special characters to a LCD. mikroE provides a tool LCD Custom Character that does this. Look under the TOOLS tab.

By what method do you get your large characters on your display ? I'm finding that using any of the "extended library" functions some users have very kindly posted here gets it done (any size font on the display) but the performance is pretty poor.

The examples shown in the pictures (240x128 T6963 GLCD) were done with SF BASIC and octal's excellent GLCD font generator. I use the large GLCD to also develop for the smaller sizes - such as 128x64 on the right.
