<p>Sorry for these multiple answers, but after thinking about this
issue, I arrived at the conclusion that we should consider the use
of unicode subscript only as a failsafe solution. In GUI mode
(Java console), we should use html output. This will solve the
problem of readability of exponents and allow many interesting
stuff, such as outputing links, ...<br>

<p>Dear Stéphane,</p>
<p>Thank you for your on-going efforts to improve the display of
polynomials and their exponents.<br>
Although i was aware about the <a moz-do-not-send="true"

<p>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>
<p>--> p = (1-%z).^(0:12)'<br>
p =<br>

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.<br>
</p>
<p>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.<br>
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.<br>
I copied/pasted a polynomial from the console into Scinotes,
zoomed Scinotes, and got the following screenshot, showing the
net difference in their sizes: :</p>
<p><img src="cid:part3.AC82BA27.2D40E44C@utc.fr" alt="" class=""></p>
<p>Without zooming, the "3" is very close to 8, and only its place
before 4 mainly indicates that it's not 8.<br>
Could the 1-3 exponents be redefined with the same size as the
other higher figures, under other unicode ids?<br>
To be investigated.<br>
<br>
Best regards<br>
Samuel<br>
