Description:
------------
iconv_mime_encode fails Q-encoding when encoding non-ascii chars,
which case is very common. This problem does not happen if line-length
is long enough to hold the encoded string in a single line.
The code use unsigned int to capture expected byte. In Q-encoding, the
value is goes to negative value (at iconv.c line 1295), and fails
separating the value into multiple lines.
Patch as following:

Reproduce code:

echo

Expected result:
----------------
a: =?UTF-8?Q?=E3=83=86?=

Actual result:
