Re: Geological symbols
For rendering, you might have a look at ConTeXt, because I recall it has an option whereby Unicode super- and sub-scripts can be displayed over each other without extra processing. > On 14 Jan 2020, at 06:44, via Unicode wrote: > > Thanks for your reply.

Thanks for your reply. I think actually LaTeX is not a good option for our purpose, because we want to create and disseminate datasets which are easy to use and do not require any software or special font installation. Thus, we’ll live with the little bit uglier version. Anyway, thanks! Thomas Von: "Jörg Knappen" Gesendet: Dienstag, 14.

I don't know how widespread the use of LateX is among geologists, but notation like this is a perfect use case for LaTeX. --Jörg Knappen Gesendet: Montag, 13.

Re: Geological symbols
It is possible with some other markup languages, including HTML by using ruby notation and other interlinear notations for creating special vertical layouts inside an horizontal line. There are difficulties however caused by line wraps which may occur before the vertical layout, or even inside it for each stacked item, and for managing the lineheight for the whole line. Finally you could endup with the same problems as those found in mathematical formulas... and for composing Egyptian hieroglyphs of Visiblespeech, for which a markup language has to be defined (with a convention, similar to an orthographic or typographic convention) in addition to the core characters that are used to build up the composition, and possibly some extra styling (to adjust the size of individual items, or to align them properly in the stack and fit them cleanly in the composition area (e.g. an ideographic square). Final difficulties are added by bidirectionality Not all texts are purely linear (unidimensional) and a linear representation is difficult to interpret without adding the markup syntax inside the source text and sometimes aven adding extra symbols (or punctuation) in the linear composition, which would not be needed in a true bidimensional layout. Unicode does not encode characters for the second dimension and the layout, so it's up to markup languages (or orthographic conventions) to define the extra semantics and/or layout. A font alone cannot guess without these conventions, and even if these conventions are used, assumptions made could infer sometimes the incorrect layout.

Re: Geological symbols
This is not possible in unicode plaintext as far as I can tell, since Unicode doesn't allow overstriking arbitrary characters over each other the way more advanced layout systems, e.g. LaTeX do. It is however possible to engineer a font to arrange those characters like that by using aggressive kerning.
