It looks like, according to errno and the iconv(3) man page [1] that errno
7 is E2BIG:

[E2BIG] Input conversion stopped due to lack of space in the output buffer.


So perhaps there's only 1024 bytes of space in the output buffer? I'll try
to dig in...

I also noticed that tds_bcp_fread is returning 0:

res 0 out_len 1024
out 1024 bytes expected 4077


which implies that it succeeded. It seems that it should return an error
code in this case? Maybe return E2BIG?
