Can NPCs speak in other languages?

[Shendare]

Is there any built-in functionality for quest NPCs to speak in /say in languages other than common? Like a quest::sayLang(12, "Hey, $name! I'm speaking in Elder Elvish!"); ? Players who were fluent in the language would see it properly, but others nearby would see a garbled message just like players speaking in unfamiliar tongues.

Also, on a related note, I know in EQLive there was at least one quest where the NPC only responded when spoken to in the proper language (Elder Dragon, I think it was). Is there currently any way for a quest script in EVENT_SAY to determine what language the player was speaking when they spoke?

Thanks in advance!
