Such integers are always in the range from 1 to 45 or 64 and can
be determined by subtracting the character space (octal 40)
from the character.

Groups of 3 bytes are stored in 4 characters, 6 bits per character.

All characters are always in range from 1 to 64 and are offset by a
space (octal 40) to make the characters printing. Character
64 represents a count of zero.
The last line may be shorter than the normal 45 bytes.
If the size is not a multiple of 3, this fact can be determined
by the value of the count on the last line.
