Odd behaviour with Plex typescript - ntg-context

30 Jun 2022


      If you load the Plex typescript, a spurious space is added on the first
switch to another font, messing up any alignment. This doesn't happen
with any other fonts; only with Plex.
MWE:
\setuphead[section][style={\switchtobodyfont[modern]}]
     \setupbodyfont[plex]
\starttext
         \section{A}
         A
     \stoptext
I was able to fix this by removing the space immediately before the "%"
on line 136 of "type-imp-plex.mkiv", changing it from this (original):
\definefontfeature[plexwideneddefault][default][extend=\luaexpr{1/0.85}] % An odd floating point number to correct monospace.
to this (fixed):
\definefontfeature[plexwideneddefault][default][extend=\luaexpr{1/0.85}]% An odd floating point number to correct monospace.
I'm pretty sure that TeX is ignoring spaces at this point, so I have no
idea why this issue exists or why the fix works.
