Proposed fix

About the proposed fix. To decide whether source type is char, you first ask whether it's char or wchar, and then compare sizeofs. I think the same can be achieved by simply asking whether src is char. I might be missing something though. That's what the patch implements.

The bug is also present in svn trunk.

The problem here, is that we have char, unsigned char, signed char, wchar_t, char16_t and char32_t types (not only char). And we still need to construct stringbuffer for char types with different sizes.

Great thanks for bug report and for giving ideas for it fixing.
