On Han unification: the Japanese reluctance to this is partly because they're being told "Some of your national literature needs to die so that our data standard can live. Deal." and partly because they're being told "What's with all the resistance, you xenophobic bastards, get with the effing program already.", generally by people who they perceive as not quite getting the issue.
All the educated Americans in the room have read Romeo and Juliet, right? Remember the balcony scene? Remember the world in the balcony scene that you have never heard in any other context?
O Romeo, Romeo, Wherefore art thou Romeo?
Imagine being told "For technical reasons, we're standardizing computers away from being able to accept 'Wherefore' as input or output. As a workaround, we suggest using "why", or perhaps putting the word in an image file and pasting it in when it is required. Most people don't use "wherefore" anyhow and, if you routinely do, you can modify your editing software to accommodate it, as long as it doesn't have to interface with any other computer ever. Oh, by the way, some other words you know are also going to stop working. It's nothing major. Well, OK, 'Gertrudes' might find it somewhat annoying but we've got a nice selection of names from Aluicious to Xavier and, if all else fails, you can spell it phonetically because your language is capable of that, too, and don't pretend otherwise."
