Think of it this way: the LyX core will deal with char32_t 
(boost::uint32). A buffer-ed stream (and all LyX's streams are buffered) 
stores its data in a streambuf. Storing these data in a streambuf<char> 
will involve a conversion on input to the streambuf. That's pointless if 
you're subsequently going to extract the data to char32_t again. Storing 
the data in a streambuf<char32_t> will result in zero conversions for 
such cases and one conversion only when writing the streambuf contents 
to file.

Altogether, it's the correct thing to do. The LyX core should eventually 
know almost nothing about 8 bit chars. The downside is that this 
solution requires a char_traits<char32_t>. If the system one isn't 
suitable LyX will need its own version.
