Hi list

rendering a very easy formula with greek text in it produces a pdf-document that has not a valid utf-8 string.

I use evince for displaying pdfs under ubuntu linux. The document appears correctly on the screen but stops printing after a greek letter in a formula.

The error-report says: Internal Error: cairo context error: input string not valid UTF-8

How are you compiling the document (mkii or mkiv) Can you attach the actual PDF as well (small attachments are allowed on the list).

The same document compiled in live.contextgarden.net doesn't produce a mistake and can be printed with evince.

contextgarden uses Mkii rather than Mkiv

Hi Hans I used texlive (2012) before standalone. There was never a problem. Same editor, same viewer. With standalone there is a problem just for printing from viewer "evince". I can print the very same document with lpr (command-line) without problem. I don't think there is a real problem with the pdf. "evince" manipulates somehow the pdf-document before sending to printer. There the error occurs. Strange that the output from context in texlive didn't have this problem. Has the output-format changed since last year? Thanks Christian 2013/6/17 Hans Hagen

Hi Aditya

I use Mkiv both standalone and live.contextgarden.net http://live.contextgarden.net**.

Document: \starttext $3v$ \stoptext

it's a 𝑣 i.e. a character with unicode 0x1D463 so it's probably a viewer/editor cut/paste issue

Hans

Just some anecdote: I was working on a presentation style last week and was getting really weird results, with background elements shifting on the page randomly. I suspected that some update had brought changes in Metapost and tried on my laptop with a slightly older version, and everything was OK. Then I installed the latest version on the laptop and tried again - still OK. After two hours of fuzzing around, I finally understood that it was a problem with evince, not with the pdf - if I opened the same file with okular or Adobe Reader, everything was fine. So I wouldn't trust evince; looks like the clowns in charge of gnome have managed to break their pdf viewer as well.

Hmmm Remind me: PDF stands for "Portable Document Format", or something else? Alan

Yes, it is very curious, but unfortunately, pdf viewers behave very inconsistently, especially on linux. When you use something like shading or transparencies, you can have very nasty surprises. Though I must say that in my experience, okular has been quite good. Adobe Reader does some funny things with colors and makes fonts look too skinny, and evince has some bizarre problems.

cut and paste from viewers depends on - documentproviding tounicode - viewer dealing with unicode - os copy buffer dealing with unicode / locales - receiving (editor, mailer) dealing with unicode / locales e.g. here - acrobat copies the proper math italic v - sumatrapdf copies nothing - okular copies a v - pdftotext output nothing so .. who knows Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
