[Bug 769827] Re: poppler cannot parse font weight "Medium"

[Michael Terry]

** Description changed:

- 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

+ 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

  Expected:
   all characters are showed properly

Title:
  poppler cannot parse font weight "Medium"

Status in “poppler” package in Ubuntu:
  Triaged

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
