Well, thät wäs a smärt cömment, yes?

To clytie:

I agree wholeheartedly with you as regards the wavering i18n support in OS X, particularly as regards the available documentation.

Even though I am not faced with anything as challenging as Vietnamese (my locale is still within the scope of ISO-8859-15), I have had extreme challenges in setting up my iBook keyboard to work like $DEITY intended, which, for my particular values of $DEITY, happens to be a mix of old Sun and PC keyboards.

Setting up a personalised keymap was fairly painless (there are a number of resources that tell you how), and in the end I found my keys in the right place, but combinations like Command - Option - whatever generate a disheartening beep. Command and Option individually work sweet.

I've resolved the issue by Not Giving a Damn. After all, there are usually menu options that give the exact same result.

But I would love Apple to provide a decent set of instructions on how to customise the keyboard layout beyond getting the Euro symbol working, without sacrificing functionality. Or it could be that I am just a bit daft, and my mind is poisoned by the flexibility and simplicity of xmodmap and Xkb.
