Yes, it happens with emacs -Q. But when I reported the bug, I forgot that since pretty much forever I had an alias for "tree" in my zsh config that aliases the tree command to "tree -AC". Removing the alias solves the problem. Fiddling shows the it's the -A option that causes the problem. So, the actual problem is that ansi-term doesn't work with tree's -A option. Given that the -A option is declared as a "hack" in tree's manual page, I don't know whether it should actually be cared about. I don't really remember what made me turn this option on in my alias. Since a few years I use urxvt as my terminal emulator, so it might have been a faulty terminal emulator. When I switched to urxvt, I probably forgot about it. urxvt never had a problem with that option, though. > Are you able to install 25.3 for testing? Yes, I just compiled it from source.

The ansi-term (and likewise, term) modes fail to properly display the
Unicode drawing characters used by the tree(1) command. Steps to
reproduce:
1. Run M-x ansi-term
2. Switch to the directory you want to tree(1)
3. Execute tree command
4. The output looks like this:
testtree
0tqq Ba
0tqq Bb
0x tqq Bb-a
0x mqq Bb-b
0mqq Bc
Whereas it should look like this:
testtree
=E2=94=9C=E2=94=80=E2=94=80 a
=E2=94=9C=E2=94=80=E2=94=80 b
=E2=94=82 =E2=94=9C=E2=94=80=E2=94=80 b-a
=E2=94=82 =E2=94=94=E2=94=80=E2=94=80 b-b
=E2=94=94=E2=94=80=E2=94=80 c
