It is quite natural to think that separating a word up into individual
characters is quite easy. It turns out that for the computer this isn’t really
the case. If we look at a system that understands Unicode (like XeTeX or
LuaTeX), most of the time one ‘character’ is stored as one codepoint. A
codepoint is a single character entity for a Unicode programme. For example, if
we take the input café, it is made up of four codepoints:
The third major release of siunitx was out in
May, after the TeX
Live 2021 DVD. That means it’s been picked up
primarily by more active users: people who install TeX between the ‘fixed’ DVD
releases (or who use MiKTeX). It also didn’t initially
appear on Overleaf, as they take a while to test TeX
Live images before making them public.
Usually, I keep my day job (as a university lecturer in chemistry) and my LaTeX
work separate. Of course, I use LaTeX at work for things like lecture handouts,
but most of the time the two areas don’t directly intersect.
With v3 of siunitx out, I am as expected
getting quite a few questions about moving from v2. In the main, this is quite
easy as there is a decent amount of compatibility code. Here, I’ll pick out
a few cases where you might want some adjustments.
Following up on the recent first beta for
siunitx, I’ve now made a second beta
available. There was only
one issue picked up so far by testers, plus of course those I’ve spotted myself.
In particular, I’ve allowed a way to set the text font manually if simply
resetting back to the standard one doesn’t work. I’ve also sneaked in a late
addition: the ability to parse and print uncertainties the way NIST seem to
suggest they should appear.
I’ve been talking about a new version of
ages. Progress has been slow but I’ve now put
my back into it and got to a feature-complete version: I’m calling this
v3.0.0-beta. As this is a beta release, it’s not ready for production just
yet, but it is ready for proper testing. I’ve made the TDS-style zip file
available here; if you
know how to use this kind of file, please download and test!
