Hi Richard,


You are right. I have tested my code a bit further and found out that
the strings that need conversion are ended with a pair of zeroes and that
those caracters were taken into account in the length.
So your test would not pass with ubuf[2] = (unichar)0 and the given
length set to 6 instead of 4 for the unicode string.

I don't know what the "normal" behaviour should be but this quite make
sense that way anyways.

Thank you!


Wolfgang
