/**
 * Parse Multi Languages Field value
 *
 * This function extracts the translation of a user-entered field value
 * Users must enter thetext in the following format:
 * default_string|lang_code:translated string
 *
 * @since 5.8.2 Fix ML default value beginning with `|locale:`.
 * @since 11.4 'ParseMLField' can be used as a DBGet() callback function to parse column
 * @example DBGet( "SELECT TITLE FROM courses", [ 'TITLE' => 'ParseMLField' ] )
 *
 * @example "My vacation by the sea|fr_FR.utf8:Mes vacances à la mer|de_DE.utf8:Mein urlaub am rand des meeres"
 *          Will display the English text unless the current language is either fr_FR.utf8 or de_DE.utf8
 *
 * @global array $RosarioLocales
 *
 * @param  string $field  Multi Languages Field value.
 * @param  string $loc    Locale (optional). Defaults to current locale (session).
 *
 * @return string Current language Field value
