   Looking at gta02-core-all.pdf on a 1280x1024 screen, I have no problems
telling nF from uF. But the nF looks disappointingly much like mF, which   
fortunately isn't likely to occur. Lower case letter are easier to separate
from digits than upper case letter, which is important because we use them
as decimal points - 1k5 or 1K5. I think I even prefer 22r over 22R.
