<application>Pango</application> is a library for laying out and rendering
|
|
text, with an emphasis on internationalization. It can be used anywhere

that text layout is needed, though most of the work on

|
<application>Pango</application> so far has been done in the context of

the <application>GTK+</application> widget toolkit.

First work around a bug in gcc-13 which triggers a false warning
|
|
that breaks a release build:

Install <application>Pango</application> by running the following

commands:

the API documentation for this package, issue:

To test the results, issue: <command>ninja test</command>. One test,

<filename>test-font</filename> is known to fail. Some tests may

fail if no Opentype or Truetype fonts are installed in
