Don't worry... ;-)

I wanted to use the UTF-8 converter in one of my own programs
and decided to do some tests before... So far only my test program
broke.

The program_options library might be affected (not yet tested!),
if options are read from a UTF-8 file which is longer than 8192
bytes and contains many "international characters" (i. e. UTF-8
sequences of two or more bytes).

Very true.

We can do both... ;-)

I'll try to find out more about this 'partial' thing. The next step would
be to make the current implementation of the conversion facet more
robust (or to fix a bug in libstdc++...?!).

If a new version of the UTF-8 facet is available it may find its way
into other libraries, e. g. program_options, serialization etc.
