locales against\n * a list of available locales.\n *\n * The algorithm is based on the BCP4647 3.3.2 Extended Filtering algorithm,\n * with several modifications:\n *\n * 1) available locales are treated as ranges\n *\n * This change allows us to match a more specific request against\n * more generic available locale.\n *\n * For example, if the available locale list provides locale `en`,\n * and the requested locale is `en-US`, we treat the available locale as\n * a locale that matches all possible english requests.\n *\n * This means that we expect available locale ID to be as precize as\n * the matches they want to cover.\n *\n * For example, if there is only `sr` available, it's ok to list\n * it in available locales. But once the available locales has both,\n * Cyrl and Latn variants, the locale IDs should be `sr-Cyrl` and `sr-Latn`\n * to avoid any `sr-*` request to match against whole `sr` range.\n *\n * What it does ([requested] * [available] = [supported]):\n *\n * ['en-US'] * ['en'] = ['en']\n *\n * 2) likely subtags from LDML 4.3 Likely Subtags has been added\n *\n * The most obvious likely subtag that can be computed is a duplication\n * of the language field onto region field (`fr` => `fr-FR`).\n *\n * On top of that, likely subtags may use a list of mappings, that\n * allow the algorithm to handle non-obvious matches.\n * For example, making sure that we match `en` to `en-US` or `sr` to\n * `sr-Cyrl`, while `sr-RU` to `sr-Latn-RU`.\n *\n * This list can be taken directly from CLDR Supplemental Data.\n *\n * What it does ([requested] * [available] = [supported]):\n *\n * ['fr'] * ['fr-FR'] = ['fr-FR']\n * ['en'] * ['en-US'] = ['en-US']\n * ['sr'] * ['sr-Latn', 'sr-Cyrl'] = ['sr-Cyrl']\n *\n * 3) variant/region range check has been added\n *\n * Lastly, the last form of check is against the requested locale ID\n * but with the variant/region field replaced with a `*` range.\n *\n * The rationale here laid out in LDML 4.4 Language Matching:\n * \"(...) normally the fall-off between the user's languages is\n * substantially greated than regional variants.\"\n *\n * In other words, if we can't match for the given region, maybe\n * we can match for the same language/script but other region, and\n * it will in most cases be preferred over falling back on the next\n * language.\n *\n * What it does ([requested] * [available] = [supported]):\n *\n * ['en-AU'] * ['en-US'] = ['en-US']\n * ['sr-RU'] * ['sr-Latn-RO'] = ['sr-Latn-RO'] // sr-RU -> sr-Latn-RU\n *\n * It works similarly to getParentLocales algo, except that we stop\n * after matching against variant/region ranges and don't try to match\n * ignoring script ranges.
