Hello Marcella,

Characters per line can be viewed in the subtitles edit box.

cf. [url removed] see number 5 under "The subtitles edit box".

The window corresponding to number 5 is locked at 219 and cannot be modified

You can define Maximum characters per line (beyond which there is a warning) in Aegisub's Options.

I changed this setting in Options to half (20), but nothing changes, the length of the line is actually at more than 40 characters.

I need lines to be no more than 23 characters. Is that allowed?
