===== What? =====
Some notes regarding linux, i18n and encoding of files.  [[https://resources.oreilly.com/examples/9781565922242/tree/master/doc|Ken Lundes cfk.inf file is very helpful.]]
===== verifying utf8 output =====
In a utf8 xterm, verifying the output of date and a utf8 file:

<code>
[chris@hive ~]$ locale -a|grep ^ja
ja_JP
ja_JP.eucjp
ja_JP.ujis
ja_JP.utf8
japanese
japanese.euc
[chris@hive ~]$ echo $LC_ALL
ja_JP.utf8
[chris@hive ~]$ cat test_utf8
日本語
[chris@hive ~]$ date
2013年 12月 23日 月曜日 22:20:21 CET
</code>

===== looking at eucjp output =====
Now the same should also work in an eucjp encoding environment. Below (incorrect) output is on Fedora19, on Debian I get proper output:
<code>
[chris@hive ~]$ LC_ALL=ja_JP.eucjp luit
[chris@hive ~]$ locale charmap
EUC-JP
[chris@hive ~]$ cat test_eucjp
F|K\8l
[chris@hive ~]$ date
2013G/ 127n 23F| 7nMKF| 22:21:45 CET
</code>
Seems to be the 7-bit equivalent of EUC-JP "日本語".

===== fedora19/20 and rhel7 issue =====

Description of problem:
  xterm does not display EUCJP encoding

Version-Release number of selected component (if applicable):
  xterm-293-1.fc19.x86_64
  (not sure if this is an issue in xterm, glibc or something else)

How reproducible:
  always

Steps to Reproduce:
1. # verify eucjp and utf8 locales exist
   locale -a|grep ja_JP   
2. # ensure this is a terminal capable of displaying the chars we request later
   LC_ALL="ja_JP.utf8" echo 日本語
   LC_ALL="ja_JP.utf8" date
3. LC_ALL="ja_JP.eucjp" luit
4. date

Actual results:
2013G/ 127n 24F| 2PMKF| 17:49:59 CET

Expected results:
2013年 12月 24日 火曜日 17:49:04 CET

Additional info:
- the above works on debian stable
- gnome-terminal and xterm both show this
- tried this in "xterm -en eucjp" terminal, as well as gnome-terminal
- in the eucjp output, the high bits seem stripped off by something
- setting "stty raw" does not lead to the expected output
- also creating a utf8 textfile, converting to eucjp with "iconv" 
  and outputting this gives same result
- the output of "date +%A| xxd|md5sum" in a "LC_ALL=ja_JP.eucjp luit"
  environment is identical on the debian and the fedora system
</code>
===== debugging =====
  * Alternatively to running "luit" manually, "xterm -en eucjp" can be used.
  * "stty raw" does not change the output
