Thank you for your reply.

I found /gnu/store/...-gtk+-3.24.0-bin/bin/gtk-update-icon-cache. Also
found /gnu/store/...-glibc-2.28/bin/locale.

Why not these command make symlink to ~/.guix-profile/bin ?

And  I did gtk-update-icon-cache -t -f --include-image-data
~/.guix-profile/share/icons/hicolor.
It return permission error that is directory read only.

I use ja_JP.utf8 locale and man page garbled in some case. I do LC_ALL=C or
posix man in that case.
