When they occur as \hyphenchar, or as a single character (e.g. \char123), everything's fine. With the EC fonts, the same happens for some quote characters. Here's a plain TeX file showing the problem: ---------------------------------------------------- \tracingoutput 1 \showboxbreadth \maxdimen \showboxdepth \maxdimen \pdfprotrudechars=2 \hsize10em \def\testprotrusion#1{#1\dotfill #1\penalty-10000} \font\testfont=cmr10\testfont \newcount\charcount \charcount=0 \loop \rpcode\font\charcount=1000 \advance\charcount 1 \ifnum\charcount < 256 \repeat \noindent \testprotrusion{A}% OK \testprotrusion{-}% \testprotrusion{--}% \testprotrusion{---}% \testprotrusion{itworks\-likethis}% \testprotrusion{\char123}% \testprotrusion{\char124}% \font\testfont=ecrm10\testfont \charcount=0 \loop \rpcode\font\charcount=1000 \advance\charcount 1 \ifnum\charcount < 256 \repeat \noindent \testprotrusion{``}% \testprotrusion{''}% \testprotrusion{\char13}% \quotedblbase \testprotrusion{\char18}% \quotesinglbase \testprotrusion{Z}% OK \bye ---------------------------------------------------- I don't know whether that might be related, but in all cases, something is being inserted between the character itself and the right margin by TeX (a discretionary for the dashes, a \kern for the quote characters). (This is the same bug as reported in the dctt thread `Randausgleich von Binde- und Trennstrich', 29.8.04) Regards, Robert. ---------------------------------------------------------------------- Comment By: Nobody (None) Date: 2004-09-29 03:39 Message: Logged In: NO In the README to the patch, you say: > To scroll back over unwanted things I now have extended > the discardable() macro.

Does that mean that `\kern1pt A\kern1pt' will not get protruded? And, what about `\kern1pt\unkern A\kern1pt\unkern'? Unfortunately, I'm not able to to test your patch. Could you (or somebody) run this file, and comment on the output, please, or upload the PDF? % ----------------------------------------------------- \pdfprotrudechars=2 \hsize5em \def\testprotrusion#1{#1 \hfill #1\penalty-10000} \font\testfont=cmr10\testfont \lpcode\font`\A=1000 \rpcode\font`\A=1000 \noindent \testprotrusion{A} \testprotrusion{\hskip0ptA\hskip0pt} \testprotrusion{\kern1exA\kern1ex} \testprotrusion{\kern1ex\unkern A\kern1ex\unkern} \testprotrusion{\kern1ex\unkern\kern1ex\unkern A\kern1ex\unkern\kern1ex\unkern} \testprotrusion{\kern1ex\kern1ex\unkern\unkern A\kern1ex\kern1ex\unkern\unkern} \testprotrusion{Z} \bye % ----------------------------------------------------- My concern is about LaTeX packages which might insert kerns as markers. For example, the csquotes package, or the footmisc package. I suppose that protrusion should take place at every point where TeX allows a line break -- is that correct?

Hi pdftex team, a user of our Debian package containing pdftex suggested some changes to the man page, along the lines of the text displayed with "pdftex --help". Dan Jacobson <jidanni(a)jidanni.org> wrote: [I pointed him to the sentence that refers the user to the "info file or manual Web2C] > f> The complete documentation for this version of TeX can be found > f> in the info file ... > $ info pdftex > gets the manpage. > > Wait, I see, you should say > > The complete documentation for this version of TeX can be found in the > Info manual Web2C: A TeX implementation. > > or something like that.

[TEXNAME[.tex]] [COMMANDS] The TEXNAME[.tex] part is missing currently.

Sorry, no patch - I don't understand how pdftex.man is generated from the m4 file. Regards, Frank -- Frank Küster, Biozentrum der Univ. Basel Abt. Biophysikalische Chemie
