In this case, these pages all seem to be generated by "rst2man" from the python3-docutils package, so I'm reassigning this there. https://gitlab.com/man-db/man-db/-/issues/26, and in particular https://gitlab.com/man-db/man-db/uploads/e7434daee5d71e37ec4cbcce892abdc5/0001-Improve-lexgrog-1-portability.patch, might be a useful reference here. This sort of relatively complicated thing is ideal for fixing properly in manual page generators so that it only has to be done in a much smaller number of places. > This issue looks similar to > > https://bugs.debian.org/1040975 The warning was made visible by the same upstream change, yes. However, the CW font at least exists in one groff device (dvi); the C font does not. As a result, I'm somewhat less inclined to work around it. Thanks, -- Colin Watson (he/him) [cjwat...@debian.org]
