<!-- ##### SECTION Title ##### -->
Coverage Maps

<!-- ##### SECTION Short_Description ##### -->
Unicode character range coverage storage.

<!-- ##### SECTION Long_Description ##### -->
<para>
It is often necessary in Pango to determine if a paticular 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.
</para>

<!-- ##### SECTION See_Also ##### -->
<para>

</para>

<!-- ##### ENUM PangoCoverageLevel ##### -->
<para>
Used to indicate how well a font can represent a particular ISO 10646
character point for a particular scrpt.
</para>

@PANGO_COVERAGE_NONE: The character is not representable with the font.
@PANGO_COVERAGE_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.
@PANGO_COVERAGE_APPROXIMATE: The character is represented as basically the correct
                             graphical form, but with a stylistic variant inappropriate for
                             the current script.
@PANGO_COVERAGE_EXACT: The character is represented as the correct graphical form.

<!-- ##### STRUCT PangoCoverage ##### -->
<para>
The #PangoCoverage structure represents a map from ISO-10646 character
point to #PangoCoverageLevel. It is an opaque structure with no public fields.
