Goooood Morning,
Does it break program_options, or does it break some use of UTF-8 that you make?
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).
Oh.... this 'partial' is messy thing.
Very true.
Unless somebody else can shed some light, there are two choices: 1. You can wait until I'm back from vacation. 2. You can figure out the exact meaning of 'partial' and send a patch.
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. Best regards, Tilman
