How does the kernel deal with foreign languages?

The question just floated into my mind yesterday and I couldn't find an answer on DDG. Userspace programs use gettext to retrieve messages by their accession number from an external file located in the /usr/share/locale tree. You can translate that file into other languages and hang them on appropriate twigs of the tree et voila a multilingual program.

But the kernel doesn't use external libraries. Does that mean that non-English speakers have to use English to make sense of dmesg output or logs?
