// %PANGO_SCRIPT_CYRILLIC is ru (Russian), the sample language for
// %PANGO_SCRIPT_ARABIC is ar.
//
// For some scripts, no sample language will be returned because
// there is no language that is sufficiently representative. The
// best example of this is %PANGO_SCRIPT_HAN, where various different
// variants of written Chinese, Japanese, and Korean all use
// significantly different sets of Han characters and forms
// of shared characters. No sample language can be provided
// for many historical scripts as well.
//
// As of 1.18, this function checks the environment variables
// `PANGO_LANGUAGE` and `LANGUAGE` (checked in that order) first.
// If one of them is set, it is parsed as a list of language tags
// separated by colons or other separators. This function
// will return the first language in the parsed list that Pango
// believes may use @script for writing. This last predicate
// is tested using [method@Pango.Language.includes_script]. This can
// be used to control Pango's font selection for non-primary
// languages. For example, a `PANGO_LANGUAGE` enviroment variable
// set to "en:fa" makes Pango choose fonts suitable for Persian (fa)
// instead of Arabic (ar) when a segment of Arabic text is found
// in an otherwise non-Arabic text. The same trick can be used to
// choose a default language for %PANGO_SCRIPT_HAN when setting
// context language is not feasible.
