Hello, @coises, @alan-kilborn and All,
I made a test :
First, disable the View > Word wrap option as well as the View > Show symbol option
Put the value 78, ONLY, in the Settings > Preferences... > Margins/Border/Edge > Vertical Edge Settings dialog
Leave the Background mode option unchecked
Then, insert this text below in a N++ new tab :
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
<<<
WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW
PPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP

Note : globally, the capital letter W is the largest letter in proportional fonts and the small letter i is the smallest letter in proportional fonts
Now, select the 78 space characters, right before the string <<<
=> You can verify that the status bar contains Col:79 Sel: 78 indication
Open the Settings > Style configurator... dialog and select Global Styles for Language and Default Style for Style
Now, click on the drop-down list of the Font name option
Use the Up and Down arrow key to select an other font
=> It easy to verify, in the status bar, that, whatever the font used, even exotic ones, the selection of the gap of space characters stays identical to the value 78
Now if, for any font, you select all the text of that new tab and run an Edit > Line Operations > Split Lines operation, for most of them, indeed, the spliting behaviour occured right after the 78 capital letter P.
However, for eample :
For the proportional Times New Roman font, the spliting action occured after 76 letters P
For the fixed witdh **``Consolas font, the spliting action occured after 77 letters P
Best Regards,
