[NTG-context] LMTX and PDF document form German »Bundesgesetzblatt«

[Pablo Rodriguez via ntg-context]

Dear list,

for some reason unknown to me, LMTX has problems with PDF documents
comming form the German official gazzette.

http://www.bgbl.de/xaver/bgbl/start.xav?startbk=Bundesanzeiger_BGBl&jumpTo=bgbl122s0928.pdf
contains one of the documents and here is a minimal sample:

  \setuplayout[page]
  \starttext
  \externalfigure[bgbl_Bundesgesetzblatt Teil I_2022_Nr. 20 vom
22.06.2022_bgbl122s0928.pdf]
  \stoptext

The source above distorts the page presentation with LMTX, but it is
perfectly fine with LuaTeX.

Could anyone confirm the issue?

Many thanks for your help,

Pablo

Many thanks for your reply, Thomas.

I’m afraid I also experience this with
https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=OJ:L_202401788
(EU Official Journal).

Even the first page displays the issue:

  \setuplayout[page]
  \starttext
  \externalfigure[OJ_L_202401788_EN_TXT.pdf]
  \stoptext

Again, LuaTeX has no issues with this document.

Just in case it might help to find the cause,

Pablo

LMTX seems to clean up the included PDF and removes the tagging
structure, but this is not properly done. There are still various

 /Artifact BMC 
 /Span << /ActualText <FEFF00AD> >> BDC 

without closing EMC around. (The /Span is from hyphens at the end of
lines and so not part of the structure tree).

The feature can be disabled with \externalfigure[...][compact=no].
