It took a while to understand how it works but it was worthy.
I try to summarize because others may find it useful:
- the "dimensions" feature is defined in font-ext.lua
- its parameters modify the footprint of the glyphs of a font
- its parameters are factors for glyph's width, height (over the baseline) and
depth (under the baseline)
- they are factors of emwidth, exheight and exheight respectively
- a value of zero for any of them means "leave the default value untouched",
dimensions={0,1.9,0} means that only the height of (the footprint of) glyphs
is set to 1.9 times exheight,
the other two dimensions stay untouched
Before looking at the code I started playing with the dimensions values
to understand what they controlled. One trial was this
\definefontfeature[default][default][dimensions={2,0,0}]
I got "spaced" text (glyphs have a larger footprint and appear spaced)
But this does not work:
\definefontfeature[spaced][dimensions={2,0,0}]
\starttext
Normal text and {\feature[+][spaced]spaced text}
\stoptext
Is it a feature that works only globally?
per font instance, so you can selectively use it

indeed, this feature gets applied to the glyphs and from then on tex
uses those dimensions

Hello list,
I'm typesetting italian text that contains "E" letters with a grave accent,
like this: "È".
In my "body font environment" the interline space is narrow and those
"È" make their lines taller, making every following line move downwards.
The problem is easily solvable putting "\smash" before "È".
But my sources are XML and typesetting is done through xmlsetups,
so I'm looking for an automatic way to replace every "È" in the text
with "\smash{È}".
Is it possible?
