In another e-mail that for some reason was not sent (and was
completely deleted...) I mentioned this page <a
class="moz-txt-link-freetext"
href="https://en.wikipedia.org/wiki/List_of_mathematical_symbols"
moz-do-not-send="true">https://en.wikipedia.org/wiki/List_of_mathematical_symbols</a>
and standard ISO 80000-2, which in its clause 9, item 2.9.5 </font></blockquote>
<p>I have well received it, but in private, and ending with this
reference, that is not public (to buy)<br>
(not sure that i can access to it from my University. Will try
later).</p>

and one without space, such as <font face="Times New Roman,

<p>Thanks for this explicitness.<br>

I like the space more, it is more general and the only situation
where it would be ambiguous is between numbers, such as 1.234 58
(since the thousand separator is a short space according to the
ISO-BIPM GUM), but between numbers × is customary.<br>

<p>It would be <i>v</i><i>ery</i> hard (and easily prone to errors,
due to many specific cases, using parentheses, etc) to parse the
input to detect all possible cases (1-char symbols, multiple-char
symbols, literal numbers with or without exponential notations,
real or complex, etc) and adapt the multiplication symbol
accordingly.<br>
<br>
We might even define a "Ts.s=2" structure field in the context,
and use it in the input. It works.<br>
