Hi Rik,
although they don’t seem to work as expected in ConTeXt, Unicode has
combining diacritical marks (as you might know), such as:
U+0301 COMBINING ACUTE ACCENT
Just in case it might help,

Indeed, for the cases where there are combining accents that is a much
better solution. I should have chosen a better example, that is, one
that does not have a combining accent. Fortunately, there are very few
that fall into that category, and unfortunately, there are some.
Using this, together with Thomas’s code, I can get around these issues.
Thank you both.
(And yes, I had attached the wrong example, and then referred to the
font therein by the wrong name.)

[NTG-context] Oddity: \buildtextaccent shifts glyph right
I am using \buildtextaccent to create a couple of characters that have
no Unicode equivalent. They are scribal abbreviations that made it into
early typesetters works. In this case, the abbreviation are for Latin
que, which looks like a q with a small ezh appended in a subscript
position, and q with an acute accent, both of which are used in some
17th century works I am dealing with. An example of the abbreviation
with the ezh and accent can be seen at
https://books.google.com/books?id=hHNVcAAJ&pg=PA6#v=onepage&q&f=false in
the sixth line of the paragraph beginning “Yea but”.
It seems that \buildtextaccent\textacute q (or \buildtextaccent´q) moves
the q to the right within the character’s bounding box. The following
example (and attached resulting pdf) demonstrates this. Lines 1 and 2
show the string with and without the \buildtextaccent, and lines 4 and 6
repeat that in italic. The strings are the same width, but the q is
moved right. Lines 3 and 6 show a manual kerning of the q to improve
appearance.
This happens with many fonts, but not all (I do not see it with Computer
Modern). I am using Win 10Pro x64 with ConTeXt ver: 2015.09.04 11:00
MKIV beta fmt: 2015.9.5 int: english/english.
I suspect that this is not intended, but I am not sure.
I would also love to raise the accent a bit. Suggestions? I can live
with it as it is and manually kern as needed. There are very few
instances of these abbreviations that need to be dealt with.
