When scaling the fonts, it seems to me, that the gap between 100 and °C
(actually its ℃=u2103), which some fonts don't have but TeX Gyre Pagella
and Asana Math do, gets smaller in relation to the overall size.
What is the reason for this?

The 'gap' here is the product marker for multiplication of the value by
the unit. This is by default a thin space, and is always set in math
mode using the current siunitx approach. You can force the use of the
text mode font with
\sisetup{number-unit-product = \text{\,}}
Yes, that helps. I have now also seen, that siunitx got updated to 2.4,
which deals with the problem of "minus" I issued at bitbuckt.
Now, the reason that this is in math mode is because I was aiming at the
case where products are actually shown as such, using \cdot or \times.
It seemed (when I initially wrote siunitx) that forcing math mode here
was the most sensible approach.
In siunitx v2.4 (current release), I dropped several of these 'always
math' ideas, and am currently seeing what feedback I get on this. *If*
this seems acceptable to users, I may alter the behaviour of the
'product-like' options to also require \ensuremath to guarantee math
mode for symbols. This would be a breaking change, and so I feel it is
best to first see how the changes in v2.4 work in practice.
I'm not sure about the defaults either, but if I say "mode=text" or
"detect-mode" & use \SI in text-mode, then I don't want any
tex-math-mode to fiddle around in the output. That often confused me in
the last time. I will try with 2.4.
Thanks
