@motonai I agree with your PR except for the (6 pixels + 2 for separating chars) part.
Normally, it should be:

• Add 1 missing whitespace after "o"
• Plus 6 whitespaces (representation of one whitespace in the provided ASCII).

So the separating spaces should be (1 + 6) instead of (2 + 6).

Here is the corrected version:

I'll be pushing ASAP. You are correct, I forgot that last space column per letter is coming from the letter itself. Thank you for your feedback.

Seems ready now :)
