I honestly don't know how you're going to use this font in
"teaching" ...
In documents and presentation files. Beginners want to assume the
one-to-one correspondence. Why in the world should some letters be
written / printed differently? (It is not wise to explain this. Come
on. They are just learning to spell the words. Plus, in exercises,
tests and exams, the mentioned font makes the letters unique, e.g. the
upper case I VS the lower case l.)
