Re: lower superscripts in MkIV -- too low?

[Otared Kavian <otared@gmail.com>]

Hi Sanjoy,

I agree with you to say that the position of subscripts and superscripts in mkiv is not perfect: the same remark applies to the position of the derivative sign « prime » as $u’(t)$.

Actually in mkii (and also in plain TeX) the positions of the superscripts in your example are the same, but this is not the case with subscripts:
	$x_{3}\ x\mathstrut_{3}$
that is in mkii the latter $x\mathstrut_{3}$ gives a lower subscript, while in plain TeX both subscripts are positioned at an identical depth.

I would say the position of subscripts and superscripts in mkiv should be identical with one gets with the latest beta (version 2014.03.20 16:59) in the following example
	\starttext
	$x\mathstrut_{3}$ and $x\mathstrut^{3}$
	\stoptext

However as Hans pointed out, regarding maths typesetting in mkiv there are also some font related issues.

Best regards: OK
