I am trying to do some subscripting, only I do not
want the char height of the subscript to be included in the list
of boxes for the line (the char width of the subscript is zero).

For example, assume I am using some font, where the width of the
char Y is zero.
Then 

X\lower0.5em\hbox{Y}

increases the line width by 50%.
What should I do to force the height of the "\lower0.5em\hbox{Y}"
to be taken as zero, so that it does not influence the line height ?

Any help will be appreciated.
As to why I need this, I have developed a font in PostScript which
I need to use in TeX. The PostScript font only contains "building
blocks", and I need to compose font characters to get the complete
language character.
I am not aware of any way to set the char height of a particular char to
zero. (Of course, it is possible to set the width to zero.) 
For example, in the case shown above, it would be sufficient if I could
set the height of the char Y to zero.

Thanks, for any help.
