When I repeat the exact same steps but first set $ export LC_ALL=en_IE.utf8 in the environment, the build goes swimmingly. I only ran each test once so it could be a coincidence, but I doubt it. As for the actual error… > ./doc/guix.ko.texi:431: here is the previous definition as @node > ./doc/guix.ko.texi:2065: @node `??????' previously defined At the risk of being naive: could it simply be that the missing locale turns the Korean UTF-8 into a literal ‘??????’, which of course matches another mangled @node string of the same length? Kind regards, T G-R
