### Detailed Description

It is often necessary in Pango to determine if a particular font can represent a particular character, and also how well it can represent that character. The `PangoCoverage` is a data structure that is used to represent that information.

### Structures

`PangoCoverage`

  The `PangoCoverage` structure represents a map from Unicode characters to `PangoCoverageLevel`. It is an opaque structure with no public fields.

### Enums and Flags

`PangoCoverageLevel`

  Used to indicate how well a font can represent a particular Unicode character point for a particular script.

  `none`

    The character is not representable with the font.

  `fallback`

    The character is represented in a way that may be comprehensible but is not the correct graphical form. For instance, a Hangul character represented as a a sequence of Jamos, or a Latin transliteration of a Cyrillic word.

  `approximate`

    The character is represented as basically the correct graphical form, but with a stylistic variant inappropriate for the current script.

  `exact`

    The character is represented as the correct graphical form.
