/**
 * Transliterate UTF-8 text to ASCII.
 *
 * Takes an input string in any language and character set, and tries to
 * represent it in ASCII characters by conveying, in Roman letters, the
 * pronunciation expressed by the text in some other writing system.
 *
 * @param $input
 *   UTF-8 text input.
 * @param $unknown
 *   Replacement string for characters that do not have a suitable ASCII
 *   equivalent.
 * @param $source_langcode
 *   Optional ISO 639 language code that denotes the language of the input.
 *   Used to apply language-specific variations and defaults to the current
 *   display language. If transliteration takes place during output (instead
 *   of creation) and the source language is not known at that time, it is
 *   recommended to set this argument to 'en' to produce consistent results
 *   for all enabled languages.
 * @return
 *   Transliterated text.
