Ubuntu 10.04下Evince漢字顯示方框或者無法顯示

Ubuntu 10.04下Evince漢字顯示方框或者無法顯示解決。Evince 原本是 GNOME 環境中一個簡單的文檔查看器，不過用來閱讀 PDF 格式的電子書倒也不錯。竊以為，Evince 雖無 Adobe 本家之 Acrobat Reader 龐大，卻有執行快速、資源占用少之優點；而與系統中另一個“古董級”的 Xpdf 相比，在界面外觀上自然要亮眼些，在操作使用上也要便當些。現在看來，實為偶家的不二之選。

Evince 支持閱讀包括英文、中文等在內的多種語言的 PDF 文檔，個人認為其效果要好過 Xpdf。且對於追求速度的用戶來說，可作為 Acrobat Reader 的替代。有此需求的朋友不妨一試。

分兩步：

1.apt-get install poppler-data

其中包含cmap-adobe-gb1

CMap files for Adobe-GB character collection, which stands for Adobe-defined one, and including standard Simplified-Chinese charsets.

2.編輯/etc/fonts/conf.d/49-sansserif.conf 為

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<!--
If the font still has no generic name, add sans-serif
-->
<match target="pattern">
<test qual="all" name="family" compare="not_eq">
<string>sans-serif</string>
</test>
<test qual="all" name="family" compare="not_eq">
<string>serif</string>
</test>
<test qual="all" name="family" compare="not_eq">
<string>monospace</string>
</test>
<edit name="family" mode="append_last">
<!-- <string>sans-serif</string> -->
<string>文泉驿正黑</string>
</edit>
</match>
</fontconfig>

注意紅色的字體，換成你希望的中文字體名。

再打開pdf文件看看。

其實也可以不改/etc/fonts/conf.d/49-sansserif.conf，而改/etc/fonts/conf.d/69-language-selector-zh-cn.conf,將你希望要的漢字在sansserif字段中提前。
最終69-language-selector-zh-cn.conf的文件內容可能如下：
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>

<match target="pattern">
<test qual="any" name="family">
