To add to physikerwelt. 

The rendering issue probably stems from the old TeX backend that does not
support Unicode well. 

Do you have any rendering issues in the new MathML/SVG option?

From a MathML point of view, the minus sign should be encoded as U+2212 (which
mathoid would generate from a regular -, whereas en dash would be kept as
U+2013 which is not ideal, e.g., for accessibility).

Danke, Peter, für diese Ergänzung. Tatsächlich wäre U+2212 das korrekte Zeichen
und sollte von TeX korrekt verarbeitet werden. (Ich hatte primär U+2013
verwendet, weil es mit Alt-0-1-5-0 und in den deutschen Standard-Sonderzeichen
bei den WMF-Projekten steht; aber da kann ich mich natürlich umgewöhnen.)

Sorry for writing in German: At the moment, the discussion isn't official, and
each contributor seems to be a German.

Not sure how+who to make some discussion official though and what means. :)

IMHO that means: The bug is marked as invalid. If someone else confirms the
problem and sets the status to reopened, the discussion is official again.

Well, it seems sensible to support this. It's just doing a replacement of
similar minus glyphs inside math. A task for google code-in? :)

I don't understand your poblem. In $\TeX$ you are supposed to use a normal -
(https://en.wikipedia.org/wiki/Plus_and_minus_signs#Minus_sign) char. If that
produces wrong rendering that must be fixed in display part and not in the
input / parser part. So the input in the math tag is what you mean and not what
you expect to see.
