dypa at bk dot ru: Please make sure you use Windows-1251 charset everywhere when you copy and paste test content. Everywhere means in browser and in text editor.
In your case I think iconv fails because you pasted the text in ISO-8859-1 charset.

I'd like to test the patch described in #50954. Is it included into any PHP build already? Sorry, I don't feel like compiling PHP from sources.


Here is one more reproduce code:

$str = base64_decode("1Ojr6ODrICLH4O/g5O3uLdHo4ejw8ero6SIgzsDOICLR7uHo7eHg7eoiIPDg5CDv8OXk8fLg4ujy/A==");

$par = array(
	'scheme' => 'Q',
	'input-charset' => 'CP1251',
	'output-charset' => 'CP1251',
	'line-length' => 74,
);

$res = iconv_mime_encode('Subject', $str, $par);

$res = iconv_mime_decode($res, ICONV_MIME_DECODE_CONTINUE_ON_ERROR, 'CP1251');
echo 'Result: Length='.strlen($res)."  ".$res."\n";
$expected = "Subject: ".$str;
echo 'Expected: Length='.strlen($expected)."  ".$expected."\n";



It says result length is 74 chars and expected is 67.
