That was the intent, yes.

Silly typo: \relax should be before \encoding, not after it.

If all glyphs in fglra8a and fglria8a are already in a slot, then 
there's no need to reencode them; just use the 8a fonts directly. This 
is related to the 8r.enc issue below.

BTW, is 8a the proper encoding variant for the Alt fonts? I suspect 7a 
would be more characteristic of what's really in there.

Sounds like you changed the total number of \setslot commands; ETX 
files are kind of fragile that way. Try LaTeXing t1fgl.etx and see how 
the slot numbers come out, then compare with an unmodified t1.etx.

Actually he doesn't, since the glyph name in the font (and thus 
everywhere on the PS side) isn't `fj' but `j'.

8r.etx, when referenced from \reencodefont{8r}{...}, tells fontinst how 
to assign slot numbers to glyphs. 8r.enc, which dvips tends to include 
in its output, tells postscript how to do the same. These two have to 
match, or some glyphs could come out wrong.

I think Plamen was thinking along the lines of you needing to modify 
8r.etx (BAD IDEA, I'd say) and then pointing out that 8r.enc would need 
to be modified accordingly.
