Spacing between letters when treated as individual variables is always a
bit fishy. In this case the math mode suppresses the fl ligature, which
seems to be present in the font, whence the spacing is off. Something like
\starttext
\math{{\it flow}_1}
\stoptext
will help ConTeXt treat it as text and improve the spacing (and in this
case make use of the fl ligature).
Define \def\flow{\text{\it flow}} if you just want to say
\starttext
\math{\flow_1}
\stoptext

I suspect that was from an earlier, bad interpretation of the opentype
math specification and that it can go away. But: much safer is to have
a big test file first using various (variable|opname) + other char
combinations.

In math-vfu we have:
if italic then
width = width + italic
end
And that is for a reason. I might be a left over from when the math
engine was redone. So I need input from Taco.

I am guessing that this is a context bug in creating a virtual font or
loading a virtual font. But I don't know how to debug this.
Hans and Taco, do you have any idea? Why is the inter-letter spacing
different in MkII and MkIV.

Definitely looks like a bug in italic correction. In principle, the
spacing with virtual fonts (mkiv) should be the same as type 1 fonts
(mkii).
But I agree with Severin that you should not be using \math{flow_1} to
represent the first flow. I hope that this example was for illustrating
the spacing bug.

Hi,
please consider this:
\starttext
\math{flow_1}
\stoptext
When compiled with MkIV, space between "f" and "l" is quite big and doesn't
look very good. Is it a bug?
