Core Sets
Combining user-defined characters is a great way to create fre-
quently used logos or fancy headings. But as you saw, defining an
entire alphabet of oversized letters uses up ASCII codes rather quickly.

to define a handful of core characters that can be combined to make
any letter in the alphabet. This requires a bit of imagination; we
present an example here to lubricate those creative gears.
