New description:
Unicode provides nice symbols which can be combined to form large
delimiters. It would be nice if we could print matrices using these,
instead of the same ASCII brackets on all the lines. So instead of
{{{
[1 2|3]
[4 5|6]
[7 8|9]
}}}
I'd like to see one of these:
{{{
⎛1 2│3⎞ ⎡1 2│3⎤
⎜4 5│6⎟ or ⎢4 5│6⎥
⎝7 8│9⎠ ⎣7 8│9⎦
}}}
Perhaps it's best to do this in small increments: start with a keyword
argument to the `str` method of matrices, then later on make this the
default. So the ticket here is only for on-demand support of this feature,
not for its automatic use by default. For later reference, see #14733
which switched the banner to Unicode, and thereby made the choice that
Sage may look broken on non-Unicode terminals.
