Sorry, Hans—I had thought that it would be very complicated to produce one, but actually it was easy:

\usemodule[simplefonts]

\setmainfont[Antykwa-Poltawskiego][protrusion=pure,
expansion=quality, 
mode=node,
              script=latn,
smallcaps]

\setupalign[hanging,hz]

\starttext

\underbar{\dorecurse{5}{\input knuth}}

\stoptext 

Note from the wiki (http://wiki.contextgarden.net/Command/overstrike):

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]{}. 

As with \overstrike, with \underbar “off target” can mean “nowhere”. 

\underbar and Latin Modern witrh microtypography works but not \underbar and Antykwa-Poltawskiego—unless one turns off microtypography.


So, if I must use \inframed—can I get it to allow for proper linebreaking/paragraphing?

In a lengthy document, \underbar occasionally has no effect. From the
wiki, I have learned that this can be rectified using
\inframed[frame=off]{\underbar{….}}. The problem is that this only works
for short text: lengthy text, say a paragraph, gets printed as a single
line.

Is there a way (a key?) that will allow \underbar to work with \inframed
or perhaps another way of getting \underbar to work 100% of the time?

no example ?
