greek chars not displayed in mathcad example

[Waluyo Adi Siswanto]

Binary package hint: evince

I created pdf of Mathcad documents with mathematical Greek variable and print pdf (using do pdf) in Windows. When I open using Document Viewer Evince in Ubuntu 8.04, all Greek characters are missing. When I print they are missing too.

[Waluyo Adi Siswanto (was-wlk)]

This is the example. If I see this file using Widows, I can see all Greek characters, but they are all missing in Ubuntu.

[Pedro Villavicencio (pedro)]

confirmed, errors i'm getting here are:
Error: Unknown character collection 'Softland-Identity'
Error: could not create truetype face

[Waluyo Adi Siswanto (was-wlk)]

How can I read that file in Ubuntu. I have tried using another document viewer PDFedit 0.4.1, but it does not show all Greek characters, they are just missing.

[Dimitrios Symeonidis (azimout)]

does not open with evince or xpdf, but acroread (in linux) opens it fine...

[Dimitrios Symeonidis (azimout)]

the font in question (Mathcad-UniMath) seems to be embedded in the document (see attached screenshot from acroread)

Confirmed that fails on the cairooutputdev on 0.10.x, works on splash both on 0.10.x and master, can't test cairooutputdev on master. Carlos can you please test?

[Carlos Garcia Campos (carlosgc)]

Yes, it fails with cairo, it even shows these error messages:

Error: Unknown character collection 'Softland-Identity'
Error: could not create truetype face

some font thing failed
Error: could not create truetype face

some font thing failed
Error: could not create truetype face

The PDF file is very broken. The font dictionary and font descriptor are setup for a TrueType font but the embedded font is a an OpenType/CFF font. It looks like the software that created this file only works with TrueType fonts but an OpenType/CFF font was supplied. The PDF writer embedded the font as if it were a TrueType font.

until today, on Jaunty 9.04 (document viewer 2.26.1, using poppler 0.10.5 (cairo)) I cannot see the greek characters.

Do not save the font file again into another temp file

I don't know why we save the font file again, but this patch fixes the problem.

[Carlos Garcia Campos (carlosgc)]

I've just applied the patch to git master.

[Dimitrios Symeonidis (azimout)]

marked as fix committed, upstream is fixed
