How do they translate 'Urianger speak' into other languages?

[Rongway]

Broadly speaking, when someone says "ye olde english", they are refering to the trope, not the language. It's shorter than saying "do they do the equivalent to saying thee and thou and putting e at the end of words we haven't done in centuries?"

Sure, but some people also don't understand that the trope is not Old English. We still get the occasional "what's with all the old english?" in both the Novice Network and the localization forum.
