Fwd: [poppler] [PATCH] Fixup LaTeX composed characters

FYI. Don't ask me what's the problem with our PDF seems to be... ---------- Forwarded message ---------- From: Tim Brody <tdb2(a)ecs.soton.ac.uk> Date: 2011/3/25 Subject: [poppler] [PATCH] Fixup LaTeX composed characters To: poppler(a)lists.freedesktop.org Hi All, Attached is a patch to address the previous problem I wrote about with pdflatex-produced PDFs that contain overlapping-diacritics/accents. This patch contains: - a table of diacritic to Unicode combining character code-points - if an overlapping character is detected checks whether the first (in stream-sequence) character is in the table - pops the diacritic off the word - appends the diacritic to the character as a Unicode combining character This does not fix \b{o} or \d{o} because TeX places them on the next line (so aren't detected as overlapping). Yes, this is an issue with pdflatex but there are 100,000s of TeX-produced PDFs for which we don't have source for ... -- All the best, Tim. _______________________________________________ poppler mailing list poppler(a)lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/poppler

Using .ttc fonts with lua(la)tex in mactex 2010
by Beingalink 07 Mar '11

07 Mar '11

I just decided to investigate this problem a bit deeper and finally found out that doing some manual changes in otfl-names.lua, enables me to use these fonts again. I tested it using "Hoefler Text.ttc". The entries in otfl-names.lua regarding hoefler text are: -------------------------------------------------------- { ["familyname"]="Hoefler Text", ["filename"]={ "Hoefler Text.ttc", 0 }, ... }, { ["familyname"]="Hoefler Text", ["filename"]={ "Hoefler Text.ttc", 1 }, ... }, { ["familyname"]="Hoefler Text", ["filename"]={ "Hoefler Text.ttc", 2 }, ... }, { ["familyname"]="Hoefler Text", ["filename"]={ "Hoefler Text.ttc", 3 }, ... }, -------------------------------------------------------- I added the actual path to the .ttc file and thus changed the entries to this: -------------------------------------------------------- { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 0 }, ... }, { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 1 }, ... }, { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 2 }, ... }, { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 3 }, ... }, -------------------------------------------------------- Doing these changes let me do the following in lualatex which didn't work before: \setmainfont[Ligatures=TeX]{Hoefler Text} I'm not a programmer so I'm not sure if the changes I did are actually safe to adopt but perhaps this can help someone to fix this issue in the repository so it will work in future versions of lua(la)tex. To be sure, I'll paste the non-shortened excerpt with the changes I did here: { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 0 }, ["fontname"]="HoeflerText-Regular", ["fullname"]="Hoefler Text", ["names"]={ ["family"]="Hoefler Text", ["fullname"]="Hoefler Text", ["psname"]="HoeflerText-Regular", ["subfamily"]="Regular", }, ["size"]={}, ["slant"]=0, ["weight"]=5, ["width"]=5, }, { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 1 }, ["fontname"]="HoeflerText-Black", ["fullname"]="Hoefler Text Black", ["names"]={ ["family"]="Hoefler Text", ["fullname"]="Hoefler Text Black", ["psname"]="HoeflerText-Black", ["subfamily"]="Black", }, ["size"]={}, ["slant"]=0, ["weight"]=7, ["width"]=5, }, { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 2 }, ["fontname"]="HoeflerText-Italic", ["fullname"]="Hoefler Text Italic", ["names"]={ ["family"]="Hoefler Text", ["fullname"]="Hoefler Text Italic", ["psname"]="HoeflerText-Italic", ["subfamily"]="Italic", }, ["size"]={}, ["slant"]=-13.5, ["weight"]=5, ["width"]=5, }, { ["familyname"]="Hoefler Text", ["filename"]={ "/Library/Fonts/Hoefler Text.ttc", 3 }, ["fontname"]="HoeflerText-BlackItalic", ["fullname"]="Hoefler Text Black Italic", ["names"]={ ["family"]="Hoefler Text", ["fullname"]="Hoefler Text Black Italic", ["psname"]="HoeflerText-BlackItalic", ["subfamily"]="Black Italic", }, ["size"]={}, ["slant"]=-13.5, ["weight"]=7, ["width"]=5, },

But tex.print removes the \par, perhaps because of | Each string argument is treated by TEX as a separate input line. Also interesting: | The very last string of the very last tex.print() command in a | \directlua will not have the \endlinechar appended, all others do. But a statement about \par filtering of tex.print() would be useful for the documentation. Minimal example (luatex --ini): \catcode`\{=1 \catcode`\}=2 \expandafter\def\expandafter\x\expandafter{% \directlua{tex.print('a \par b')}% }\show\x \csname @@end\endcsname\end Result: "a b" Yours sincerely Heiko Oberdiek
