i think - i see 1 pixel difference.
Notepad v7.5.1’s default font is “Courier New” which may not be the greatest, but for the characters being discussed they are fairly distinguishable:
Even if I zoom in on what you are seeing I don’t see any difference in any of your characters–well…maybe…hmm. But why play a guessing game? As @Claudia-Frank strongly hinted your best course of action is to choose a different font. What font are you using, anyway? Are you sure it is the default? (See below for how to check the setting)
You want what is known as a fixed-pitch font. A monospaced font, also called a fixed-pitch, fixed-width, or non-proportional font, is a font whose letters and characters each occupy the same amount of horizontal space. This contrasts with proportional or variable-width fonts, where the letters and spacings have different widths.
Perhaps the simplest way to set up a new font is to go to the Settings (menu), select Style Configurator…, choose Language = Global Styles, choose Style = Global override, tick the box for Enable global font and then choose a new font in the Font name dropdown.
I use the Consolas font which makes it easy to distinguish between 1 and l :
But there are other good font choices as well. Here are some picked off of conversations in other threads:
Deja Vu Sans Mono
