Am I correct in my conclusion that there isn't an easy way of creating a custom character set for the Apple II? I've Googled around and can't really find any info on this.
Coming from the Commodore 64, I assumed it was as common on the Apple II. Google reveals replacement ROMs, as well as type-in programs like COMPUTE!'s SuperFont which seem to utilize the HGR mode to provide custom characters. (Conversely, it also appears that it isn't easy to put text on the HGR screen, but there are several websites which cover that topic.)
