As I said in my message: use the dest arg so as to "decode from a unibyte buffer into a multibyte buffer", so `destination' should be ... a multibyte buffer. As for why it's the only reliable method, it's because: >> Dealing with "bytes in a multibyte buffer" or with "non-ascii chars in >> a unibyte buffer" (as is necessarily the case either as source or as >> destination if you do the decoding in-place) is just too delicate in my >> experience (and of course, it's also somewhat inefficient). I'm not sure which part of the above paragraph is unclear. Stefan
