// Detects a language of the UTF-16 encoded zero-terminated text.
// [in] detection_tables - internal CLD data tables (see compact_lang_det.h).
// Can be NULL, in this case CLD will fall back to builtin static tables.
// [in] text - UTF-16 encoded text to detect a language of.
// [in] is_plain_text - true if plain text, false otherwise (e.g. HTML).
// [out] is_reliable - true, if returned language was detected reliably.
// See compact_lang_det.h for details.
// [out] num_languages - set to the number of languages detected on the page.
// Language counts only if it's detected in more than 20% of the text.
// [out, optional] error_code - set to 0 in case of success, Windows
// GetLastError() code otherwise. Pass NULL, if not interested in errors.
// See encodings/compact_lang_det/compact_lang_det.h,
// CompactLangDet::DetectLanguage() description for other input parameters
// description.
// Returns: Language enum.
// Returns NUM_LANGUAGES in case of any error.
