This information is all covered in much more detail elsewhere on the web but for my own future reference, here’s a primer on doctypes, compatibility modes, charsets and fonts which was required to explain why certain Chinese characters weren’t showing up in IE8. Of course the best answer is that you need to have the East Asian Font pack installed and then it just works (usually) but this tends to be useful background and saves “server side” folks from a number of gotchas.

i18n trap #1: I should have a simple way to map an Enum to a presentable string.

This seems eminently reasonable at first glance – there are many cases where you have one of a set of things and need to inform the user which one you have. Unfortunately human language, unlike their computer language counter-parts, are context-dependent. So that single Enum value in code could well be presented with many different words when presented as part of different sentences or in different contexts.
