Description
The new hd44780 driver contains embedded fonts. The data for these fonts are contained within the hd44780 class in luma.lcd.device.const.py in a dict called FONTDATA. One key in FONTDATA is 'mappings' which is a list of two dicts (one for each of the two fonts that are typical for hd44780 style devices). Each dict contains a collection of key value pairs which provide unicode values for as many of the table values as I could decode. I'm looking for help to fill in the missing values and validate that I've correctly assigned the ones that are there. I'd also be interested in any look-alike values that should be added (e.g. unicode codepoints that look the same as a mapping that already exists. A good example of that would be the series of cyrillic mappings I've included for their english equivalents.
Here's a small example of what the tables looks like...
