[Bug 769827] [NEW] poppler cannot parse font weight "Medium"

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Nobuto MURATA (nobuto):

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.
See attached screenshot.

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:
 1. intall Ubuntu in Japanese(ja) locale
 2. confirm poppler-data, ttf-takao-{mincho,gothic} installed and "/etc/fonts/conf.d/69-language-selector-ja-jp.conf -> /etc/fonts/conf.avail/69-language-selector-ja-jp.conf" symlink created.
 3. open attached PDF file

Expected:
 all characters are showed properly

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