Hi
Thanks for your comments
<<<it's a white space, and as such invisible (the most strikeout or underline
fonts can void this precedence).>>
It is not just about the whitespace. The point is that width of line is more
than rectangle width. So if you draw multiline text with left alignment, the
left most letter(not whitespace) would be slightly cut.
Now about removing whitespace from end of line. If you don't remove them from
the end of line, you have to make the next line start with whitespace. My
observation from office tools like MS Office, and Libreoffice is that they
don't allow lines to start with whitespaces(Except for the first line). This is
a cosmetic decision( but I guess it is common decision, the behaviour is
already part of the function). But obviously we are losing some information
from input string.
What about adding one more parameter to the arguments to decide whether lines
should be allowed start with whitespaces(or trailing whitespaces should be
skipped)?
Regards
Ali

Hi,
it's a white space, and as such invisible (the most strikeout or underline
fonts can void this precedence).

I'm afraid that the function cannot do this. Simply because it doesn't have
enough information about the meaning of the content it is supposed to split. It
might be better to left the decision up to the caller, aka let it remove
trailing white space on their own, if needed. The use case for this is an ASCII
graphics, like tables. You might break it this way in certain cases.
Bye,
