It works, and seems to be the easiest solution.

Just for completeness, let me mention a couple of others:

1) Use a space-filled leader instead of a space character:

     Where is the text<fo:leader leader-length="0.5em">?

This is equivalent to the NBSP solution; it has a disadvantage
of greater verbosity but lets you control the distance from the 
text to the question mark in a precise manner.

2) Add some padding before the question mark:

     Where is the text<fo:inline padding-left="0.5em">?</fo:inline>

Same advantages/disadvantages. This one is natural if your 
question mark should be made more visible to the Marketing:

  Where is the text<fo:inline padding-left="6pt" color="red"
                        font="16pt bold Impact">?</fo:inline>
