Dear List,
I am writing a paper in Hungarian, that I Sweave and than pdfLaTeX.
Everything is fine, except for two accented letters in the graphs that
behave strange, though on the screen and in eps exports they look
perfect. The problem is that I need pdf graphs, since I would like to
have a PDF after LaTeX-ing.
For the example below I downloaded the following two font sets:
1. Latin Modern from http://www.ctan.org/get/fonts/lm.zip
2. Computer Moder Super from
http://www.ctan.org/get/fonts/ps-type1/cm-super.zip
Both are specifically made for Eastern European languages (among many
other).
The example is (I hope it is fully reproducible):
Thanks for the clear example. A couple of changes, fixes, and
explanations included below ...
Sys.setlocale(category="LC_CTYPE", locale="hungarian")
On Linux, that needs to be something like ...
Sys.setlocale(category="LC_CTYPE", locale="hu_HU.utf8")
LM <- Type1Font("LM", paste("lm/fonts/afm/public/lm/", c("lmb10.afm",
"lmbx10.afm", "lmbo10.afm", "lmbxo10.afm"), sep=""))
pdfFonts(LM=LM)
postscriptFonts(LM=LM)
CMS <- Type1Font("CMS", paste("cm-super/afm/", c("sfrm1000.afm",
"sfrb1000.afm", "sfti1000.afm", "sfsl1000.afm"), sep=""))
pdfFonts(CMS=CMS)
postscriptFonts(CMS=CMS)
#Default
pdf("tryfont-default.pdf")
grid.text("gg\u151hh\uF6ii\uF3jj kk\u171ll\uFCmm\uFAnn")
dev.off()
#The u151 and the u171 characters "slips into" the characters following
them ("h" and "l")
For me, with Adobe Reader, on Linux, u151 and u171 are just missing, but
the root problem is probably the same; the PDF reader is probably
substituting a font and not using the default font because the real font
is not embedded in the file. The "slippage" you are seeing is probably
due to the fact that the metrics (size of each character) are completely
wrong in the substituted font so the characters are drawn in the wrong
positions.
postscript("tryfont-default.eps")
grid.text("gg\u151hh\uF6ii\uF3jj kk\u171ll\uFCmm\uFAnn")
dev.off()
#everything is perfect
#CMS
pdf("tryfont-cms.pdf", family="CMS")
grid.text("gg\u151hh\uF6ii\uF3jj kk\u171ll\uFCmm\uFAnn")
dev.off()
#u151 and u171 doesn't show, though the other accented ones do
embedFonts("tryfont-cms.pdf",
outfile="tryfont-cms-embed.pdf",
fontpaths="/cm-super/afm/")
#after embedding the same "slipping" occurs
The 'fontpaths' argument describes where the PFB files are, not where
the AFM files are. So this is probably failing to embed the fonts
because it can't find the fonts. Does it work if you change to
something like ...
embedFonts("tryfont-cms.pdf",
outfile="tryfont-cms-embed.pdf",
fontpaths="cm-super/pfb/")
In your PDF reader, see if you can find a "document properties" or
something similar; that should tell you whether the fonts have been
embedded or whether the reader is substituting a different font.
On Linux, you can use pdffonts to find out. For example, for me (look
at the 'emb' column) ...
$ pdffonts tryfont-cms.pdf
name type emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
SFRM1000 Type 1 no no no 9 0
$ pdffonts tryfont-cms-embed.pdf
name type emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
PPLABU+Times-Roman? Type 1C yes yes no 10 0

grid.text("gg\u151hh\uF6ii\uF3jj kk\u171ll\uFCmm\uFAnn")

postscript("tryfont-LM.eps", family="LM")
grid.text("gg\u151hh\uF6ii\uF3jj kk\u171ll\uFCmm\uFAnn")
dev.off()
#same as CMS
After trying all this, I am out of ideas.
Could anyone suggest a solution?
