The edges of the WWW symbol need to align with the old symbol if they are doing it right.
The && also breaks out of alignment. Alignment is the whole reason I am using mono-spaced fonts.
My history:
IBM VGA (strange j, h, k, etc.),
Courier,
Bitstream Vera Sans,
Lucida Sans Italics (only proportional font, but it looked great at the time),
Consolas,
Kids Play.
Some aspects of 'math' came along with arabic, but Roman Numerals work fine for their situation, at that time.
In conversation, it's just the I-M/0-1000 range for instance, learning how to notate that number is a different issue.
Notation is somewhat straight-forward: When you get to 4, the number undergoes a state change to 'subtract from the next number, dropping everything behind it, and we're in a new state so "the" number is changed to 5' so III becomes IV. Otherwise, just keep adding 1. That should work, adding to the previous rules as the state changes. Going to X leaves the V rules in place.
