This can be a solution, but I'm still would like to get the long deprecated (and no longer part of upstream) layout library removed. Especially that the third party addition to extend its support is dead as well. > I see that you added libiculx63, but there is no libicu-lx-dev.

Therefore the cycle is still fully present. In order to > break it, the -dev package must be split as well.

The only package still needs paragraph layout is openttd. Its upstream said Debian should drop its use[1] immediately. I do Cc its maintainer Matthijs and if he acknowledges I will drop libiculx and icu-le-hb altogether. Regards, Laszlo/GCS [1] https://github.com/OpenTTD/OpenTTD/issues/6922#issuecomment-427666586
