(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:<texcode>\setupalign[hanging,hz]bla bla bla \inframed[frame=off]{\overstrike{striked}} bla bla</texcode> * Turn off microtypography for the paragraph containing the overstrike. Example:<texcode>\setupalign[nothanging,nohz]bla bla bla \overstrike{striked} bla bla \setupalign[hanging,hz]bla bla bla bla bla</texcode></cd:example> <cd:example title="Various parameters demo"><context source="yes" text="Gives:">\setuppapersize[A5] \definebar[BarA][color=red,rulethickness=1.4] \BarA{BarA}\blankHello \startbar[BarA]\input{knuth}\stopbar world!\blank \definebar[BarB][color=green,rulethickness=2.8,order=background] \BarB{BarB}\blankHello \startbar[BarB]\input{knuth}\stopbar world!\blank \definebar[BarC][color=blue,rulethickness=2.8,order=background,offset=1.5,continue=yes] \BarC{BarC}\blankHello \startbar[BarC]\input{knuth}\stopbar world!\blank</context></cd:example><cd:example title="Underbar for clozes"><context source="yes" text="Gives:">\definebar[ClozeBar][underbar][continue=yes, color=black, offset=-0.5] \starttexdefinition unexpanded Cloze #1 \startbar[ClozeBar] \scratchdimen\widthofstring{#1}\relax \zwj\kern.2\scratchdimen #1 \kern.2\scratchdimen\zwj \stopbar\stoptexdefinition \startTEXpageThis is a \Cloze{\color[red]{cloze}} whose underbar is 1.4 times as wide as the text above it. \Cloze{The leading} and trailing spaces are never broken.\stopTEXpage</context></cd:example>
