Hello,
Altough I am the author or this patch, I find this may be a bit too
early to make the hypothesis that Scilab would be systematically
launched in an environment that allows Unicode chars.
This hypothesis is not needed to go on with Unicode in terminal modes
and improve things about this. On windows, including the code page
setting in the Scilab binary as proposed by Antoine is a first
interesting and required step.
This could be, at least, a rendering option (BTW we need an unified
way of customizing display in the preferences tab).
Allowing and even using an UTF-8 font in Scilab NW and NWNI modes should
not be an option. It should be the default.
However, using a one line display seems an improvement to me, it
allows a much better rendering of polynomials and rationals (see
https://codereview.scilab.org/#/c/21142/).
Because exponents are really too small, and because the console can't be
zoomed interactively with a shortkey and the mouse wheel, in term of
readability, the current status is clearly the best:
--> (1-%z).^(0:4)
ans =
2 2 3 2 3 4
1 1 -z 1 -2z +z 1 -3z +3z -z 1 -4z +6z -4z +z
In term of compacity, indeed using Unicode exponents is a good idea.
Unfortunately, with some fonts like Consolas, all exponents are so small
wrt to the base font size that i use to use that some of them become
hardly distinguishable.
--> (1-%z).^(0:4)
ans =
1 1 -z 1 -2z +z² 1 -3z +3z² -z³ 1 -4z +6z² -4z³ +z⁴
But this can be worked around by increasing the font size (from
Monospaced 14 to 16, for me).
Maybe a intermediary step would be to use a hat notation, e.g.
--> p=(1+%i+%s)^7
p = 8-8i -56is -(84+84i)s^2 -140s^3 -(70-70i)s^4 +42is^5 +(7+7i)s^6 +s^7
Definitively not. It turns crowdy. Keeping the current 2-line display
would be better, even if it's less compact vertically.
Regards
