Bug Description

The poppler library cannot parse font weight "Medium". Therefore in Japanese(ja) locale, characters which are not font-embedded but specified as "GothicBBB" are shown as squares and not readable.

GothicBBB is widely used as Japanese sans-serif(gothic) font. It has the full name "GothicBBB-Medium-Identity-{H,V}" in properties window on such as Evince. But poppler library cannot parse "Medium" string, so does not hit <string>GothicBBB</string> in fontconfig settings on /etc/fonts/conf.d/69-language-selector-ja-jp.conf.

On the other hand, Ryumin which is widely used as Japanese serif(mincho) font has the name "Ryumin-Light-Identity-{H,V}", but does hit <string>Ryumin</string>.

How to reproduce (assuming that you're not starting in Japanese locale):
1. Run Language Selector and install Japanese support.
2. sudo apt-get install poppler-data
3. sudo fontconfig-voodoo -s ja_JP
4. Open attached PDF file:
https://bugs.launchpad.net/ubuntu/+source/poppler/+bug/769827/+attachment/2086089/+files/g_non_emb.pdf

Expected:
all characters are showed properly

Actual:
upper-right characters which are specified as GothicBBB are showed as squares

I can confirm the problem in lucid. Japanese locale is not necessary.

I have tried to forward this to upstream, but already reported as https://bugs.freedesktop.org/show_bug.cgi?id=36474. It mainly handles other problems (properly fall back to Japanese font when font does not have Japanese glyphs), but contains my patch too. What should I do?

Nobuto-San, I think you've already done all you can (and more). The next steps that I see are to get the patch applied to natty and then hopefully backported to at least lucid. But that's out of your and my reach, we need to wait for sponsors to pick it up which I'm sure they will soon.

I'm dropping the milestone and nominating for natty as an SRU because this is too late to make it into natty proper. I'll request that this be put into oneiric once that opens and make the bug changes for an SRU for natty.

I have confirmed that the patch works. Nobuto, the only change I would suggest is that you also run update-maintainer in your package directory to make sure that the Maintainer field is accurate when we make Ubuntu changes in a package. Of course, that wasn't your fault, but Martin Pitt's when he first diverged.

Here is a version suitable for natty-proposed (just version and pocket change). I don't have upload rights for the poppler package, so I will ask that a core-dev please upload this for me to natty-proposed.

Made sure the patch also applies to lucid's codebase and then sponsored Nobuto MURATA's SRU to lucid-proposed.
Will show up once a SRU team member approves it.
