Hi Harshula! I am sorry, it seems I missed your reply.

No, I have never used it, but the library was installed because of
emacs-snapshot and it will always be installed on my primary sid because
of that (or emacs23 or emacs24 or whatever).
FWIW, however, I have already written in Japanese katakana on a terminal
Emacs using ttf-unifont.

Every time these programs run? I have not seen any Emacs error in more
than 6 years of use because of m17n-db not being installed on my sid (I
have APT's Install-Recommends off and pay attention to most extra
packages are installed as Depends:).
As a side note, now that I looked for, it is funny what upstream thinks
about the relationship between the m17n library and database, from
libm17n-0/1.6.1-1 /usr/share/doc/libm17n-0/README.gz:
(2) DATABASE
The m17n library utilizes the m17n database available at:
http://www.m17n.org/m17n-lib/m17n-db
Without this database, the m17n library loses half its value. Please
install it (Ver.1.4.0 or the later is required) too before you try the
above sample programs or develop a program that uses the m17n library.

To which I fully agree.

Exactly, but at least libpango1.0/1.28.3-4 in experimental had the
following in its description:
Recommends: x-ttcidfont-conf
Suggests: ttf-japanese-gothic, ttf-japanese-mincho, ttf-thryomanes,
ttf-baekmuk, ttf-arphic-gbsn00lp, ttf-arphic-bsmi00lp,
ttf-arphic-gkai00mp, ttf-arphic-bkai00mp
Anyway, given that:
- you reassigned this bug to m17n-db instead of libm17n-0
<http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=37;bug=604926>
- it seems you consider the libm17n0's Depends: on m17n-db and
m17n-contrib (solution for #599643) a must
NB1, funny that the original submitter of #599643 asked for an
explication of these Recommends: (which is IMHO the correct
solution) or a downgrade to Suggests:...
NB2, I would have re-opened #599643 instead, but then I found this bug
and I thought the two were linked, thus it sounds more logical to
me replying here, at least until Bill corrected me
- it seems I am the only one who cares about 8MB of disk space, maybe it
reminds me of the 512MB SD card I had for Debian on my Openmoko (and
yes, there are Openmoko owners using Emacs on it)
...I will stop complaining with this mail.
Thx, bye,
