If you're writing your own IDE for J, then see sample code at: http://www.jsoftware.com/jwiki/IanClark/LoBrow
LoBrow makes a legible char array from not just an explicit verb but any J word. To do that it handles each case separately. See the verb: repn (which mainly uses 5!:5), called by: item2panel. But the reverse operation, broadly comparable to []FX, is done using 0!:111 -which works for everything. Provided you handle your "character matrix" as a LF-separated string. Or 0!:110 if you don't want it to display in the session window.
