Very subjective but am I the only one who wishes that the spaces replaced with underscores for clarity picked a character that's easier to count consecutive runs of? Every time I see ____ I need to highlight part of the string to figure out how many underscores it has.

[hugovk]

Yes, perhaps ---- or ···· would be better?

[methane]

Although it was easy to read in the text editor, it becomes difficult to read several characters when viewed in a browser because multiple underscores are connected.

Since we are using ---> to represent TAB, how about using . to represent spaces?

[encukou]

Or use ␣ (Open Box/␣)

[hugovk]

A simple . is good, and it's easy for people to type in the DPO thread. Thanks!
