 // do the best it can and put the result in the output buffer. The versions that
 // return strings ignore this error and just return the best conversion

 // a mess to do it all at once.  These conversions should be used when we
 // really should just be passing a string16 around, but we haven't finished
 // porting whatever module uses wstring and the conversion is being used as a
 // stopcock.  This makes it easy to grep for the ones that should be removed.
