If you are using microtypography with <code>\setupalign[hz,hanging]</code>, 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 <code>\inframed[frame=off]{}</code>. Example:
bla bla bla bla bla
