Hi,
You can try this below (from test suite), but then, as you see, also
upright T will move out. Not sure how/if you can control that.
\startluacode
local classes = fonts.protrusions.classes
local vectors = fonts.protrusions.vectors
classes.rik = {
vector = 'rik',
factor = 1,
}
vectors.rik = table.merged (
vectors.quality,
{
[0x0054] = { 0.35, 0 }, -- T
})
\stopluacode
\definefontfeature
[default]
[default]
[protrusion=rik,expansion=quality]
\setupalign[hz,hanging]
\showmakeup[line]
\showglyphs
\startbuffer
Here is a line of text, the first sentence in the demonstration.\\
{\em Then} the next sentence in the paragraph follows.\\
You can see that the italic {\em T} appears to be a bit indented.\\
{\em There } might be a way to shift it to the left that little bit.\\
Perhaps a protrusion setting.\\
{\em This} does appear to depend to on the font used. With Modern and\\
Libertinus it is worse, with Times a bit better.

In a paper I recently wrote I noticed some ugly zigzag alignment on the left margin of one paragraph (set with Libertinus) where a couple of book titles appeared at the start of the second and fourth lines. The following example demonstrates the issue.
\definefontfeature [default] [default] [protrusion=quality,expansion=quality] \setupalign [hz,hanging]
\startbuffer Here is a line of text, the first sentence in the demonstration.\\ {\em Then} the next sentence in the paragraph follows.\\ You can see that the italic {\em T} appears to be a bit indented.\\ {\em There } might be a way to shift it to the left that little bit.\\ Perhaps a protrusion setting.\\ {\em This} does appear to depend to on the font used. With Modern and\\ Libertinus it is worse, with Times a bit better. \blank \stopbuffer
\starttext Modern\\ \getbuffer Times\\ \setupbodyfont[times] \getbuffer Libertinus\\ \setupbodyfont[libertinus] \getbuffer \stoptext
How can one set a small left-margin protrusion for the italic T and possibly other characters? I know it is a small issue, but once seen it is hard to un-see.
