This would also be useful for PAG review; I keep saying that something new is propertywise like some existing thing, but I end up checking that by staring at the...

Is `unisift_IsIgnorable` intentionally different from Default_Ignorable_Code_Point?

So, now that I can run the sifter, I still need to update unidata.txt for it to actually do something useful. I gather this is the relevant documentation? https://github.com/unicode-org/unicodetools/blob/main/docs/uca/ducet.md

Perhaps not code ad-hoc for H2O, but the ability to select from a range of smoke compositions, these being defined in a separate cfg containing the phase diagram etc. would...

Well, there's no way to have this phase diagram without having lots of data (we're not doing computational chemistry). Hardcoding large splines is silly, so we should load them. At...

CO2 exhaust also seems relevant, e.g., it freezes on Titan.
