This functionality IMO only makes sense as a constructor (esp. for 
immutable OUString), like

   rtl::OUString::OUString(sal_Unicode value, sal_Int32 count);

and probably some underlying C function like

   void rtl_uString_newFromValueAndCount(
     rtl_uString **, sal_Unicode value, sal_Int32 count);

However, I would also be sceptical that there are that many places that 
actually need to construct such an (immutable!) string---maybe at least 
some of the places are misguided attempts at preallocating some buffer 
of a given length?  Those should then be rewritten to use 
rtl::OUStringBuffer instead.
