Actually, NAPLPS is infinite precision. The 4K standard, and similar earlier
standards, are just sets of minimum parameters that terminal designers
should hope to have. A 4K page on a 256 terminal will draw properly,
although all the text sizes you used may not be there so you might get some
ugly wrappings, etc.

NAPLPS's character sets are fairly complete, especially when you are using
the kanji extensions.

NAPLPS on an IBM is quite good, especially with the Revolution 9 or similar
graphics board.

I have heard a rumour that the NAPLPS package for the Commodore 64 is free,
or at least sold at some extremely low price like 10$.
