Hello Samuel,
I'm agree with you about the issue.
I will try to find a way to change the console properties inside binary
like when we change color in nw mode ( W/B vs B/W )
But I does not show trouble with 2 or 3 and others superscript numbers.
With this configuration

Dear Stéphane,
Thank you for your on-going efforts to improve the display of
polynomials and their exponents.
Although i was aware about the potential issue
<http://bugzilla.scilab.org/show_bug.cgi?id=4236>, i did not catch it
before your first commit <https://codereview.scilab.org/21100> was
recently merged.
Actually, some trial on the master shows what we could expect on
Windows: Setting exponents in unicode breaks the display of
polynomials in NW (and NWNI) modes:
--> p = (1-%z).^(0:12)'
p =
1
1 -z
1 -2z +z┬▓
1 -3z +3z┬▓ -z┬│
1 -4z +6z┬▓ -4z┬│ +zÔü┤
1 -5z +10z┬▓ -10z┬│ +5zÔü┤ -zÔüÁ
1 -6z +15z┬▓ -20z┬│ +15zÔü┤ -6zÔüÁ +zÔüÂ
1 -7z +21z┬▓ -35z┬│ +35zÔü┤ -21zÔüÁ +7zÔü -zÔüÀ
1 -8z +28z┬▓ -56z┬│ +70zÔü┤ -56zÔüÁ +28zÔü -8zÔüÀ +zÔü©
1 -9z +36z┬▓ -84z┬│ +126zÔü┤ -126zÔüÁ +84zÔü -36zÔüÀ +9zÔü© -zÔü╣
1 -10z +45z┬▓ -120z┬│ +210zÔü┤ -252zÔüÁ +210zÔü -120zÔüÀ +45zÔü©
-10zÔü╣ +z┬╣Ôü░
1 -11z +55z┬▓ -165z┬│ +330zÔü┤ -462zÔüÁ +462zÔü -330zÔüÀ +165zÔü©
-55zÔü╣ +11z┬╣Ôü░
-z┬╣┬╣
1 -12z +66z┬▓ -220z┬│ +495zÔü┤ -792zÔüÁ +924zÔü -792zÔüÀ +495zÔü©
-220zÔü╣ +66z┬╣Ôü░
-12z┬╣┬╣ +z┬╣┬▓
This is a blocking issue. IMHO, the fix proposed by Allan clearly
improves the situation, but is not completely clean as it is
implemented in the launching batch file, while calling directly the
binary will shortcut the patch.
Another issue is about the readability of exponents 1 to 3: they were
likely the first defined, before other figures, but they are clearly
smaller than other exponents 0 and 4-9.
Reading them was almost OK for me in the commit message, but on the
Scilab console, i had to increase the font size from Monospaced 13 to
Monospaced 15 to get them (almost) readable.
I copied/pasted a polynomial from the console into Scinotes, zoomed
Scinotes, and got the following screenshot, showing the net difference
in their sizes: :
Without zooming, the "3" is very close to 8, and only its place before
4 mainly indicates that it's not 8.
Could the 1-3 exponents be redefined with the same size as the other
higher figures, under other unicode ids?
To be investigated.
Best regards
Samuel
