New Comment:
I'm not sure this is a dup of #48289 because I could not reproduce the
test case. So I created a separete report. If you are sure this is a
dup
of #48289, please mark this as "Duplicate" not "Bogus". Bogus means
"the
report was not a bug at last".

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same.
Thank you for your interest in PHP.
See bug #48289

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:
