Error message: Invalid UTF-8 sequence (sometimes since update in last 3-4 weeks)

I am beyond embarrassed. After 2 (unnecessary) re-installs, it turns out I had just confused 2 separate commands in my VIM editor. Thank you for answering so quickly and not treating me like the idiot I was. -- Kind regards Jacqui Coosner Cell: 083-252-7483

Error message: Invalid UTF-8 sequence (sometimes since update in last 3-4 weeks)
by Jacqui Coosner 17 Sep '18

17 Sep '18

Good day Disclaimer: I am a beginner, and I apologise upfront if there is a simple answer to this question that I should have known. Today I tried to compile an existing .tex file, and I received the following error message: /tex error on line 6 in file /Users/jjc/wrk/ctx/brx-test.pdf: ! String contains an invalid utf-8 sequence/ It's been about 3 weeks since I last experimented with ConTeXt. I am running on MacOS High Sierra 10.13.6, and I have not had an OS update since I last ran ConTeXt. I tried the following: 1) I tried to compile another file, which previously compiled successfully, and I had the same problem. 2) I then created a very simple .tex file (\starttext Hello World \stoptext ), and again I had the same problem. 3) I checked the format of my .tex file in 2 different editors to ensure that it is utf-8. (I normally use MacVim and it is clearly displaying the file format as utf-8 at the bottom of the editor) 4) I updated my ConTeXt installation, restarted my Mac and tried again. The only difference was that some of the output stream was displayed after the error message. 5) I checked the log file for my simple file, but could not find any information to help me. The log file looks as follows: /open source > level 1, order 1, name '/Users/jjc/ctx/tex/texmf-context/tex/context/base/mkiv/cont-yes.mkiv' system > system > ConTeXt ver: 2018.09.13 17:41 MKIV beta fmt: 2018.9.17 int: english/english system > system > 'cont-new.mkiv' loaded open source > level 2, order 2, name '/Users/jjc/ctx/tex/texmf-context/tex/context/base/mkiv/cont-new.mkiv' system > beware: some patches loaded from cont-new.mkiv close source > level 2, order 2, name '/Users/jjc/ctx/tex/texmf-context/tex/context/base/mkiv/cont-new.mkiv' system > files > jobname 'tmp', input './tmp.pdf', result 'tmp' fonts > latin modern fonts are not preloaded languages > language 'en' is active open source > level 2, order 3, name '/Users/jjc/wrk/ctx/tmp.pdf' tex error > tex error on line 6 in file /Users/jjc/wrk/ctx/tmp.pdf: !

list of figures
by Andrea Valle 14 Sep '18

14 Sep '18

Dear all, I have a very simple question. How do I get a list of figures? I have figures placed with e.g. \placefigure{S. Reich, {\em Piano Phase}.}{ \externalfigure[img/chap01/2][width=\textwidth]} I tried \showexternalfigures[alternative=a] it gives me back no list and this on the body text [alternative=a] Thanks Best -a- -------------------------------------------------- Andrea Valle -------------------------------------------------- CIRMA - StudiUm Università degli Studi di Torino --> http://www.cirma.unito.it/andrea/ --> http://www.fonurgia.unito.it/andrea/ --> http://www.flickr.com/photos/vanderaalle/sets/ --> http://vimeo.com/vanderaalle --> http://andreavalle.bandcamp.com --> andrea.valle(a)unito.it -------------------------------------------------- "This is a very complicated case, Maude.

A bit of wiki news
by Taco Hoekwater 14 Sep '18

14 Sep '18

Hi all, At the ConTeXt Group Meeting in Sibřina, we have given quite a lot of thought to the ConTeXt wiki at wiki.contextgarden.net. Main points from those deliberations: * We plan to remove all mkii content from the wiki. Mkiv has been around for a long time now, and the few die-hard mkii users we have left can find their documentation in the old mkii ConTeXt manuals. There is no need any longer to keep all that outdated information in the wiki, especially since it is likely to confuse new users. * Various people already offered to help improve both structure and content of the wiki. Current plans include: rewriting the installation pages, creating a Document Topics overview page, testing the examples, adding a ‘for dummies’ template at the top of typesetting-related pages, and creating new pages with helpful hints for specific font(-families). * The mediawiki software will be updated soon(-ish) to the latest version, and we plan to develop a new theme at the same time. The current theme will probably not work any more after the update anyway. To make all of that go smoothly, a new mailing list has been created for people willing to help make the wiki be (even) better than it is today. If you are willing and able to help with those improvements, then please subscribe to the ‘wiki’ mailing list here: http://lists.contextgarden.net/mailman/listinfo/wiki Best wishes, Taco

Issues with hyphenation with latest beta 2018.09.12
by Joseph Canedo 13 Sep '18

13 Sep '18

Hello, Typesetting some documents I notice several overfull boxes and having a look to output document it looks that somehow no hyphenation at all is performed (comparing to document produced with previous beta). I use thiese settings linked to hyphenation \setupalign[hanging, lesshyphenation, hz] \language[fr] % french hyphenation \mainlanguage[fr] In some places I use ‘morehyphenation’ align option and still no hyphenation at all. Any setting has changed by any chance ? Thanks a lot Best regards Joseph

coupling node name to xmlsetup
by Hans van der Meer 13 Sep '18

13 Sep '18

Suppose we have node <example> and want to execute the xmlsetup: mysetups:examplehandler on it. The idea is not to hardcode this but to do it on the fly from <definesetup name=“example”>. The following \xmlsetup comes into mind: \startxmlsetups mysetups:definesetup \xmlsetsetup{#1}{\xmlatt{#1}{name}}{mysetups:examplehandler} \stopxmlsetups \startxmlsetups mysetups:examplehandler ... \stopxmlsetups But this is either the wrong call or there is something missing, because on input of <example/> the examplehandler is not invoked. How to? dr. Hans van der Meer

wildcard selection in xmlfilter
by Hans van der Meer 12 Sep '18

12 Sep '18

There is a difference of behaviour in \xmlfilter between (1) \xmlfilter{#1}{node/command(xmlsetup)} and (2) \xmlfilter{#1}{*/command(xmlsetup)} (3) \xmlfilter{#1}{*/*/command(xmlsetup)} In case (1) the lpath ‘node’ results in processing of the <wildcard> nodes in all child nodes. In case (2) and (3) no more than the corresponding level is searched. Thus there is a difference in behaviour between node and * as an lpath. Very unfortunate for me, because I need to process all nodes regardless of theeir node name, but selected on the basis of an attribute: \xmlfilter{#1}{*[@attribute==“yes”]. The difference in behaviour makes this impossible, because a general proceudre is impossible and doing a search with * and */* and */*/* etc. always will be one level too short, I expect. Is this intended behaviour, and if so, is there a general solution? dr. Hans van der Meer

Estonian language support
by Clyde Johnston 11 Sep '18

11 Sep '18

I am clear whether Estonian (language code: et) is supported in ConTeXt. According to the manual ("languages-mkiv.pdf"), I should be able to see the installed languages using \showinstalledlanguages. Unfortunately, it does not seem to produce the desired table. However, a scan through the source code shows existence of './texmf-context/tex/context/patterns/mkiv/lang-et.lua' file. It looks like much of the work, such as hyphenation, has been already done. MWE 1: \usemodule[languages-system] \loadinstalledlanguages \showinstalledlanguages MWE 2: \starttext \language[et] \currentlanguage \stoptext I suppose my question is more general: what information does the user need to provide in order for a language to get support in ConTeXt? The manual states "More languages can be defined. It is up to users to provide the information." Thanks, Clyde

Printer requires vectorised contour path for cut contour
by Marco Patzer 11 Sep '18

11 Sep '18

Hi! I created a non-rectangular shaped document. The printer requires a cut contour in a particular colour, no problem so far. However, he complained about a missing “single continuous closed vectorised contour path”. The one I provided is an area, not a contour path. I created the path as follows: \starttext \startMPcode draw origin -- (50mm, 0mm) -- (60mm, 20mm) -- (10mm, 20mm) -- origin; \stopMPcode \stoptext Any clue how to create such a vectorised contour path? Marco

Planned wiki downtime
by Taco Hoekwater 11 Sep '18

11 Sep '18

Hi all, We plan to update the software installation on ‘my’ server on Monday Sept 24. As a consequence, various context-related sites including wiki.contextgarden.net and modules.contextgarden.net will be down for some as-of-yet undetermined amount of time. We’ll try to be fast, but one never knows with these things... It is for a good cause: we need the server software update to be able to update the wiki software later on. Best wishes, Taco
