Is the test is trying to do the same as this?

Is it basically to test that the sequence 0xC290 (UTF-8 for U+0090 control
character) is converted to 0x90 in ISO-8859-1?

It's curious that tds_iconv seems to fail (with errno 7 - what's that?)
when it's only 1024 bytes into the string; still in the middle of all the
'a' characters; it hasn't gotten to the special character yet it seems.
