the fact that you have pieces in mkii is a side effect of dvitomp 
turning dvi output in mp pictures; in the process it combines glyphs 
that have no kerning and whatever spacing becomes shifts

in mkiv the text is treated as a whole and that will not change

so, if in mkiv you want pieces, you need to textext each snippet that 
you want as such

keep in mind that the way mkii (read: external tex processing and 
dvitomp) works is quite unpredictable
