Comment 13 for bug 1411149

Seems like the UI font used on Windows XP does not have this character (em quad) and therefore shows the Unicode character code (U+2001)... I'll check if I can find an alternative that also works on Windows XP.

If anybody know of a better way to produce empty vertical space in an .inx please let me now (I already tried an empty description and an description only containing a simple space character both of which were stripped from the output)
