LPIC-1 107.3: Localization and internationalization

A second locale, what it changes, sort order, and converting a file from Latin-1 to UTF-8.

Before you start

The lab writes a short list of words in mixed case to /root/words.txt. The de_DE.UTF-8 locale must not be installed yet; the lab refuses to start if it is.

Tasks

1. Install the de_DE.UTF-8 locale. Compare date, ls -l and printf "%'d\n" 1234567 under it and under your normal locale, with LC_ALL= in front of each. Write what the printf prints under de_DE.UTF-8 to /root/lab-answers/1.
2. Sort /root/words.txt under LC_ALL=C into /root/lab-answers/2-c, and under LC_ALL=de_DE.UTF-8 into /root/lab-answers/2-de, and compare.
3. Make a Latin-1 file with printf 'caf\xe9\n' > /root/latin1.txt, check it with file, look at it with cat, and convert it to UTF-8 with iconv as /root/utf8.txt.

Hints

• RHEL family: dnf install glibc-langpack-de. Debian and Ubuntu: locale-gen de_DE.UTF-8 (or uncomment it in /etc/locale.gen and run locale-gen). Check with locale -a. Start a new shell after installing it.
• LC_ALL=C sort /root/words.txt > ...; diff the two.
• iconv -f LATIN1 -t UTF-8; file on both files.
