[pdftex] Problems with microtypographic extensions (and specific older pdfTeX versions?)

[Frank Küster]

Hi pdfTeX people,

in our Debian BTS we have a problem report about \pdfadjustspacing and
\pdfprotrudechars.  In the previous Debian stable release with an
ancient pdfTeX, the user simply put 

\pdfadjustspacing=2
\pdfprotrudechars=2 

in his preamble and observed positive effects.  Now with the release of
Debian sarge, we have a still ancient, but newer version of teTeX
(2.0.2) with pdfTeX (Web2C 7.4.5) 3.14159-1.10b, and he reports that
this stopped working.  A current pdfcprot.sty from CTAN seems to work
with this pdfTeX version, but it only does character protruding, no
space changes and thus no altered linebreaks.

microtype.sty is supposed to do both, but with teTeX-2.0.2 the user gets
an error when the expanded font is created:

kpathsea: Illegal fontname `aer12+20': contains '+'

Since the user reports that adjustspacing has worked even with
teTeX-1.0.7 in Debian woody, there should be some way to do it in
teTeX-2.0.2.  Do you have any tips how it should be done?

Thanks in advance,
Frank
