Yes, you break the fact that for many objects you can copy/paste the
output to get your object back
sage: %display plain
sage: integral(gamma(x), x)
integrate(gamma(x), x)
sage: eval("integrate(gamma(x), x)")
integrate(gamma(x), x)
but
sage: %display unicode_art
sage: integrate(gamma(x), x)
⌠
⎮ Γ(x) dx
⌡
sage: u = integrate(gamma(x), x)._unicode_art_()._repr_()
sage: eval(u)
File "<string>", line 1
⌠
^
SyntaxError: invalid syntax
And what about doctesting?

Okay. So let's say that we enable ascii_art by default: is there a
unintended consequence? Or should we just do that?

There is no bulletproof way for the program to determine whether the

have been using unicode in the startup banner for years without problems.
I'd just assume that it works by default nowadays.
%display unicode_art also renders symbolics as art
sage: %display unicode_art
sage: integral(gamma(x), x)
⌠
⎮ Γ(x) dx

which should be the default in any system that tries to attain new users.
Whereas this is how you dissuade potential new users:
sage: integral(gamma(x), x)
integrate(gamma(x), x)

Would it be safe to enable unicode_art on startup if it is supported?
Or does it mean that many objects will be displayed with drawings
instead of their usual representation as a consequence?
I am trying to figure out *how* to display matrices in unicode by
default when it is supported.
