> We're getting a few warnings for the __rw_utf8toucs4() inline function indicating that the function is too big to be inlined. It might be a good idea to split it up into two, a simple inline wrapper to handle the common case for single and perhaps two-byte characters and a bigger out-of-line implementation to handle the more complicated multibyte characters.
