No, that's "old Type 1" as opposed to "new OpenType/CFF", the 21st  
century way of using Postscript curves to draw glyphs!

Of course, if you have traditional Type 1 fonts, you may be using  
them with TFM files, fontmap entries, etc., and all that should still  
work. But that doesn't bring you into the Unicode world.

One thing that I have in mind is to enable xetex to read an AFM file  
along with a PFB, and thus support kerning for such fonts, but I'm  
afraid this hasn't reached the top of the to-do list yet....

If FontForge or other software can import the kerning data from an  
AFM file (I assume your Type 1 fonts came with AFMs), and then  
include that in an OTF version, then yes.

I'm fairly sure FontLab can do this (though I've never tried); I  
don't use FontForge, so can't speak for it, but my guess is that it  
probably has such a feature.
