Base ASCII plane from the character generator ROM of the ST7036 LCD controller, built as a fixed pitch font. This is missing the characters mapped on 0x00 through 0x1f, the first half of which could be user-defined characters loaded in RAM at run time, and hence really difficult to define in a font. I've also left off the katakana characters mapped from 0x80 to 0xFF, as I don't need them for my current requirement.

All charcters are 5x7 dots in a 6x8 dot character cell. All 6x8 dots are implemented on the panel, and the panels typically provide blank columns and rows between character cells, so I'm not entierly sure why the standard ROM image doesn't ever use the 6th column or 8th row. To mark the cell boundaries, I've included tick marks in each corner where that pixel is blank. If no extra leading or tracking is applied, those ticks will abut.

I've defined all of the obvious space characters to be blank, and also defined the Unicode NOT SIGN (U+00AC) as a blank to make it easier to draw screen images.
