It is working now but I needed to do some changes on your code.

When you check charset_utf8 and charset_trans you have a problem on attachments case. Attachments part do not have any charset defined on headers so, by default, charset_utf8=1 and charset_trans is garbage (I have no idea where that garbage came from).

To avoid this problem swap the some lines of code that set ctx->binary_input to the function's beginning.

Please see the attachment to checked any problem that may exist.

Thank you,
Rui Carneiro
