xpdfで日本語が表示されない [解決]

たった，いま気がついた．
エラーの情報．

% xpdf ~/doc/univ/2009/rinko.pdf
Error: Couldn't open cidToUnicode file '/usr/share/xpdf/Adobe-Japan1.cidToUnicode'
Error: Unknown character collection 'Adobe-Japan1'
Error: Couldn't find a mapping to Unicode for font 'Ryumin-Light-Identity-H'
Error: Couldn't create a font for 'Ryumin-Light-Identity-H'

設定等．

displayCIDFontTT        Kochi-Gothic    /usr/share/fonts/TTF/VeraSe.ttf

そして，/usr/share/xpdfを覗いてみると…

% ls /usr/share/xpdf
CMap  EUC-JP.unicodeMap  ISO-2022-JP.unicodeMap  Shift-JIS.unicodeMap

見事にAdobe-Japan1.cidToUnicodeが無い！ナンテコッタイ /(^o^)\

ところでVeraSe.ttfってなんぞ？

% ls /usr/share/fonts/TTF/VeraSe.ttf
ls: cannot access /usr/share/fonts/TTF/VeraSe.ttf: そのようなファイルやディレクトリはありません

貴様もか！ \(^o^)/
これで表示されたら奇跡．

という訳で，自分でパッケージつくるYO!
ABSのやつを流用させて頂く．

% cp -r /var/abs/extra/xpdf-japanese .

PKGBUILDを次のように編集．ほとんど，そのまま．Adobe-Japan1.cidToUnicodeとフォントだけ変更．

}

とりあえずフォントはIPAゴシック．IPA明朝でも，もちろん良いのだけれど，ゴシック体のほうが
自分はなんとなくだが，見やすい気がする．

そして，

% makepkg
% pac -U xpdf-japanese-20040727-5-any.pkg.tar.gz

で完了．

めでたし，めでたし．

# 修正後に気がついたのだが，自分，xpdfなんて使わなくね？ epdfviewだよねいつも．
