Hm. I think we may not be talking about the same thing after all.
If we're talking about the Curses library, or something similar,
this is not the same. I do not think Curses has support for
combining characters, right to left text, wide characters, etc.
However, Unicode does, and defines the column width for those.
I have an illustration of what this looks like in the picture
in the very last recipe, #44, in
http://training.perl.com/scripts/perlunicook.html
That is what I have been talking about by print widths. It's running
in a Mac terminal emulator, and unlike the HTML which grabs from too
many fonts, the terminal program does the right thing with the widths.
Are we talking about different things?
