did you see how it's implemented? The dirty PS tricks are in a header
that should only be used by dvips or clever rasterizers as gsftopk (I
_have_ bitmaps of this dotlessj generated this way). So any viewer or
dvi driver should call the original (dolessj-less) fonts. ATM
compatible etc. The problem is: what do the dvi drivers when the tfm
says a chrachter exist in a type1 font and it doesn't? I suppose they
should leave a white space according to the advance width: do they?

Isn't it a pitty that there is no system level support for postscript
fonts in windows, indeed?
