Pango是一种特定用途的文本函式库,而不是像同样能被Pango所用的通用图形渲染库Cairo只具备最简单的文本渲染。实际上Cairo技术文档推荐使用Pango来渲染文本。
应用
Pango已经被整合到多数Linux发行版中,并在Fedora Core 6被用于Firefox网页浏览器和Thunderbird邮件客户端的文字渲染。虽然在Mozilla的源代码里并没有包含Pango,但Fedora Core得到了Mozilla基金会的特别许可[6]。同样,Debian的Iceweasel、IceDove和IceApe也使用了Pango。
对OpenType功能的支持
Pango 1.17及更新版本支持使用locl标签允许同一Unicode码点的本地化字符的使用。

- Abdin, Ali. . beast.testbit.eu. 27 December ???? [2015-10-17]. (原始内容存档于2013-06-02). Pango (which is the code name for a merger of my Gscript project and Raph Levien's GnomeText project) is a modular set of libraries for doing layout and rendering of international text. It's a bit similar to Microsoft's Uniscript or Apple's ATSUI.
