That might be useful for those depending on it, and presumably there is a
\stackscripts, too. Just comes to my mind:
Though probably non-standard in typesetting, one might make a slight
typographic difference between 푥²₀ and 푥₀² by letting the sub- or
superscripts that come later partially, but not fully, to the position of
the one that comes before. For example, 푥₀² might mean the square of 푥₀,
and 푥²₀ the component 0 of 푥², not necessarily the same. Traditionally,
such things are left for the reader to interpret.

Indeed. It came to my mind, because I started to think about a good ways to
represent sub- and superscripts in a parser.

Your suggestion might be great for simplifying tensor component notation, as

If you mean tensor component notation, that is different, as any component can be shifted. In pure math, one is more likely to see them stacked, also for tensors in differential geometry, as one typically indicates their type somehow. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

I thought such a feature would be suitable, but I am not sure now to get the
math glyph override with the \definefontfallback command (see example below).
With \definefallbackfamily there is an extra argument for the style:
\definefallbackfamily
[mainface][mono][stixtwotext][range={00B2-00B3,00B9,02070-0208F},force=yes]
Otherwise, the use of monospace has several functions: Signaling it is computer
code, allowing indentation, and allowing a tabular style. Maybe it should not
all be put on the font (editing it by hand with markup may be tedious and error
prone).
An incidental remark: TeX puts simultaneous sub- and superscripts above each
other, and the Unicode sub- and superscripts are translated as such in the
example below math mode. But actually, there may be a semantic difference
between the order (though not in the case below), and that is used in tensor
notation. In TeX, the original suggestion is to use {} in such a case.

Using monospace to make some computer code stand out as such. It would suffice with select portions, though, like some keywords. > Sorry, but I’m afraid that ConTeXt doesn’t spaces as glyphs. Right, but for a monospace font in verbatim mode, one might expect it. Maybe there should be a monospace option for the fallback. > Would it be easier that you use a proper mono font for typing? Do you have any suggestions? —There is no such font covering the several thousands of glyphs used in math, and I am not sure it would help readability. Monospace somehow got popular for code in the ASCII range. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Hi Hans,
what are you trying to do?
Sorry, but I’m afraid that ConTeXt doesn’t spaces as glyphs.
Would it be easier that you use a proper mono font for typing?

[NTG-context] Monospace fallback kerning
In the example below, multiple spaces do not use the spacing of the fallback
font for multiple spaces, but instead of the main font it seems, despite the
ASCII U+0020 being in the forced override. So the question is how to force
ConTeXt to use the fallback font also for multiple spaces.
