A quick tip from a community member (hat tip Yann Guidon) saved some space. Since each character of the font begins with the character width, and each character is one-byte tall, the null terminator is redundant. We can infer this information already from the width.

This reduced the font size about 90 bytes, and saved the program about 70 (additional code to process this change). Will do some code cleanup to try to realize some more savings.
