If you are using microtypography with \setupalign[hz,hanging]
, then with some fonts the rule may end up off-target, above the characters instead of through them. (The problem was experienced with Linux Libertine and mkiv, and not with Latin Modern.) The workarounds are:
- Put the overstriked text in a
\inframed[frame=off]{}
. Example:
\setupalign[hanging,hz] bla bla bla \inframed[frame=off]{\overstrike{striked}} bla bla
- Turn off microtypography for the paragraph containing the overstrike. Example:
\setupalign[nothanging,nohz] bla bla bla \overstrike{striked} bla bla \setupalign[hanging,hz] bla bla bla bla bla
