Re: [NTG-context] \unit and Hertz, lux, and degrees/minutes/seconds
On 18/11/2011, Pontus Lurcock
Degrees, minutes and seconds of arc (also degrees Celsius) are an exception and are not supposed to have any space between the digits and the degree symbol [1], so to be correct, I think Context should by default veto any space between digits and numbers, in these cases only.
Correction, I should have written "(but not degrees Celsius)", apologies.
Conventions for setting the degrees of temperature symbol vary; see http://en.wikipedia.org/wiki/Degree_symbol#Typography and references therein. In most professionally published works that I've seen, there is no space between the number and the °, or between the ° and the C.
Pont, I agree they vary, and no space before the °C is quite common (and frequently my own practice too). However in setting default behaviour for Context I am inclined to favour conforming to international standards, where they exist (but a \setupunits override it probably called for). Robin

I have no opinion as to what the default behaviour should be, but it would certainly be useful to have spacing for ° temperature configurable separately from that for other units. Pont

so, best is that those asking for it come up with a list of issues: which symbols need this option, is it language related or whatever, so that i can do them all at once. We can already have different mapping sets so spacing could be part of that.

I don't personally have a need for units in the foreseeable future (I was just nitpicking with Robin about spacing) so feel free to ignore any of my suggestions, but I think the summary so far would be: 1. Spacing for almost all SI units should be the same and doesn't need special cases. 2. Geographical degrees/minutes/seconds should have no spaces. 3. Spacing for degrees temperature varies according to different style guides -- both before and after the ° -- so ideally it would be possible to set these independently of the rest of the units. For my own part I would add: 4. SI unit abbreviations are mostly capital letters, and look (to me) strange with old-style figures. I have seen books which used old-style figures for page numbers, years, etc. but switched to lining figures when a unit was involved; this is also what I did in my thesis. So I think it would be useful to allow an automatic switch to lining figures to be configured when typesetting a unit. Pont
