And especially for resolving what looks like quite a complex issue in next to no time. As it happens I've found LMTX just fine for "production", so long as I keep copies of a few versions that I know are working well. I settled on SciTE a long time ago and tend to keep a few start up scripts that make reverting to a previous version simple: -r-x------ 1 rbm49 rbm49 210 Dec 20 16:54 SciTE-start-lmtx-20200920.sh -r-x------ 1 rbm49 rbm49 210 Jun 13 22:04 SciTE-start-lmtx-20210509.sh -rwx------ 1 rbm49 rbm49 210 Jun 15 08:50 SciTE-start-lmtx-latest.sh #!/bin/bash #=C2=A0 # =C2=A0SciTE-start-lmtx-20200920.sh PATH=3D"${HOME}/lmtx-20200920/tex/texmf-linux-64/bin:${HOME}/lmtx- 20200920/bin:${HOME}/bin:${HOME}/.local/bin:/opt/VirtualBox:${PATH}" cd /home/rbm49 && exec /usr/local/bin/SciTE && exit 0 exit 2=20 But really, taking things back a version or two isn't needed all that often as issues tend to be sorted out quite quickly with all the testing that people are doing -- so thanks for that too. :) Best, Richard --=20 T +6433121699=C2=A0=C2=A0M +64210640216=C2=A0=C2=A0E rmahoney@indica-et-bud= dhica.org IM https://t.me/rmahoney=C2=A0=C2=A0W https://indica-et-buddhica.org/ Indica et Buddhica=C2=A0=C2=A0Littledene=C2=A0=C2=A0Bay Road=C2=A0=C2=A0Oxf= ord=C2=A0=C2=A0NZ -----Original Message----- From: Hans Hagen Reply-To: mailing list for ConTeXt users To: Richard Mahoney , mailing list for ConTeXt users Subject: Re: [NTG-context] [#1] CJK regression? | lmtx-20210613 &c.

The problem is that we=20 need to deal with the previously reported clash between different=20 unicode entries that share shapes (normally no issue but in this case it=20 was a side effect of 'effective' monospaces where the font decided that=20 invisible shapes should he visual anyway) as well as with the fact that=20 soem cjk fonts have many duplicates which makes us cross the 65 boundary. The variant approach is ok but I might have overlooked some soecial=20 cases. Because this also drops 'stream compatibility' between mkiv and lmtx (which had already become somewhat loose) I can now also clean up (simplify) some other parts of the font system but let's do that=20 stepwise (I'm in no hurry here).
