Jim, behaviour will depend on fonts being used. It could also depend on the version of software you are using. Windows 7 has pretty good support (fonts and Uniscribe) for all of this.

Yes, I realize this, too. I was referring to the specific case of East Asian-script characters in NFD, not the general case of characters in any script in NFD. In Notepad, I see an o with a macron on top of it for the Unicode characters U+006F U+0304. On the next line of the same text file, there are the two Unicode characters U+30C8 U+309, but I do not see a katakana letter do. Instead, I see a katakana letter to and, to the right of it, a katakan-hiragana voiced sound mark. I observe essentially the same thing in other applications, including BabelPad and SC UniPad. So this is this specific circumstance that led me to ask the Unicode community about a specific case: Asian-script characters in Unicode Normalization Form D. The answer for my specific case (thanks to Doug Ewell) is that the version of Uniscribe installed on my computer is not properly rendering katakana and Hangul characters in Normalization Form D. It seems I need a better Uniscribe. The other valuable thing I learned is that there are plenty of systems (complex systems of computer and similar digital device hardware, video display devices, computer operating systems, software applications, font-rendering and text-layout service applications, fonts, etc.) that support Unicode in Normalization Form D better than the systems I'm using at the moment. I didn't know this. Thank you for the additional information about Latin-script NFD. Jim Monty
