I am pasting here Havoc's original explanation of the move to UTF-8 as posted to
this list a month ago:

The reasons for Unicode include:

 - so you can use multiple languages at once in a document

 - so that programs can write a single generic algorithm 
   for say word breaking, instead of special-casing each 
   locale

 - because most of the modern apps (all Qt, GTK apps, most scripting
   languages, etc.) are using Unicode internally, so using it
   externally speeds things up

 - so that Chinese/Japanese/Korean are going through the same
   codepaths as European languages, so that there are fewer
   CJK-specific issues. (Of course we don't default to UTF-8 for CJK
   yet, but it's coming.)

 - because the filesystem needs to be in UTF-8 unless all users
   of a system are using the same language exclusively

FWIW, the issues people are seeing with UTF-8 are almost all things
that Asian users have been living with for years... now everyone's in
the same boat, let's patch the leaks. ;-)

Hope this helps. Sounds to me as if the implementation was meant to
make coding easier for multi-language systems rather than to make things 
easier for individual single-language users.  I suppose that will come when
the whole world is using Unicode.
