\DIFdel do not wrap

[jiezhangMars]

the text in the \DIFdel cannot wrap, but that in the \DIFadd could.

I used latexdiff in texlive2021. What if the long sentence need to wrap?

This is unusual and not the behaviour seen before. I have many examples where this works fine. I have never tried in TexLive2021, though; it is possible this brought to light a bug in ulem which is the package used by default for doing the actual highlighting. Maybe other Texlive2021 user can chip in if they see the same behaviour. As a workaround I can suggest to use a different markup type (Option -t), which does not use ulem.

The same problem occurs in both texts in \DIFdel and \DIFadd in TeX Live 2022 on Ubuntu.

老哥你最后有解决吗？ @jiaqiwang969

Not sure if OR is still watching this, but to make any progress I would need an MWE (minimum working example) that shows this effect, i.e., the full latex files, old and new, needed to recreate that effect (and ideally stripped of everything else), preferably in English. As I don't see this effect I suspect some interference between ulem and other packages included. Maybe using lualatex with LUAUNDERLINE option (which was added since this post made) already solves the problem.
