Re: Adding /dotlessj to Type 1 fonts

["Berthold K.P. Horn" <bkph@ai.mit.edu>]

   I've found a clever way to add the /dotlessj character to
   existing Type 1 and Type 5 fonts.

Clever indeed, but unfortunately not useful for a large part of the TeX world. 

The reason is that all such `PostScript trickery' manipulations are
*not* device independent.  Don't forget that `PostScript' fonts are
actually used on screen, and with non-PS devices on several platforms
(Windows and Mac).  And ATM compatible Type 1 fonts are no longer ATM
compatible after you wrap some PS code around them.

Not everything in Tex is done by first converting to PS and then
rasterizing using a PS rassterizer...
