Description Jan "Yenya" Kasprzak 2005-11-24 21:54:21 UTC

When rendering the PDF from http://info.muni.cz/images/pdfmuni/muni07.pdf,
evince displays incorrect letters (even instead of pure US-ASCII characters).
The letters are in the correct font, but not the right letters. I have
originally reported this as an evince bug at
http://bugzilla.gnome.org/show_bug.cgi?id=322118 - but I was asked to report
this as a possible poppler bug. Xpdf renders the above PDF correctly
(screenshots of both xpdf and evince rendering this document are attached to the
above bug in the GNOME bugzilla - I may reattach them here as well if there is
an interest).

This is with evince-0.4.0, poppler 0.4.1, system is Fedora Core 4 Linux (tested
on AMD64 and i386 versions).

Fixed in CVS HEAD.

I can still reproduce this bug with current (2005-12-08) CVS of evince and
libpoppler.  The pdf from the first comment is shown ok now, but <a
href="http://www.library.cornell.edu/nr/bookcpdf/c5-7.pdf">this document</a> for
example still show the problem.

Reopening the bug.

Comment 5 Kristian Høgsberg 2005-12-10 07:06:56 UTC

What version of freetype are you using and which distro?

Comment 6 Kristian Høgsberg 2005-12-10 07:12:24 UTC

Also, could you try out cvs head, there's different fix for the bug there.

Comment 7 Bas Zoetekouw 2005-12-10 07:15:37 UTC

I'm using libfreetype6 version 2.1.10 on Debian unstable.

Comment 8 Bas Zoetekouw 2005-12-10 07:16:21 UTC

I tested it with CVS head.  Or do you mean libfreetype cvs?

Comment 9 Kristian Høgsberg 2005-12-10 08:03:35 UTC

I meant poppler cvs head, specifically a version that has this change:

	* poppler/CairoFontEngine.cc: Correct fix for #5149, i broke it when
	merging xpdf 3.01 patches.

Comment 10 Bas Zoetekouw 2005-12-10 08:11:17 UTC

Yes, I used a checkout of this morning, which has your commit:

Comment 12 Christian Kirbach 2005-12-10 09:28:08 UTC

I am using freetype 2.1.7 on Debian testing and can confirm the garbled text.

When opening a file in question the terminal reads

Error: Couldn't find a font for 'Times Roman'
some font thing failed
Error: Couldn't find a font for 'Times Bold'
...

jhbuild checks out like this
 cvs -z3 -q -d :pserver:anoncvs@cvs.freedesktop.org:/cvs/poppler update -dP -A .

I hope it is cvs HEAD.

Now, I had to upgrade to freetype 2.1.10 because of undefined references.
It is still reproducable :(

Comment 13 Christian Kirbach 2005-12-10 09:31:39 UTC

seems so - the enty appears in the Changelog.

Comment 14 Christian Kirbach 2005-12-14 01:49:11 UTC

I have dicovered that latex documents converted to pdf using dvipdf are 
displayed with garbled characters *if the "Times" font is used*. If I switch to 
other fonts (e.g. bookman,newcent, or the default latex font) I cannot see that 
behaviour.

Hope this may be of any help.
freetype 2.1.10

Comment 15 Brad Hards 2007-12-04 01:56:08 UTC

Is this still a problem? The link in comment #4 is broken.

Comment 16 Bas Zoetekouw 2007-12-04 15:18:19 UTC

An alternate download location for the link in comment #4 is http://www.fizyka.umk.pl/nrbook/c5-7.pdf

It displays perfectly with evince 0.9.0 and poppler 0.5.4 (Debian sid)

Comment 17 Brad Hards 2007-12-05 18:19:29 UTC

Original reporter confirmed now OK.
