It the right answer is: create ru_RU templates?

[tanya]

At first check default_charset in phpini
After you can modify needed files. Also check file charset

[dimyy]

Unfortunately you are not right.

Problem is in old version of zend-mail included in distrib.

Old version of function

public static function canBeEncoded($value)
{
$encoded = iconv_mime_encode('x-test', $value, ['scheme' => 'Q']);

return (false !== $encoded);
}

on string 'Post: [Задача] Расширить права на ПК' return wrong answer, but fresh function from zend-mail (https://github.com/zendframework/zen...rWrap.php#L140)

public static function canBeEncoded($value)
{
// avoid any wrapping by specifying line length long enough
// "test" -> 4
// "x-test: =?ISO-8859-1?B?dGVzdA==?=" -> 33
// 8 +2 +3 +3 -> 16
$charset = 'UTF-8';
$lineLength = strlen($value) * 4 + strlen($charset) + 16;
$preferences = [
'scheme' => 'Q',
'input-charset' => $charset,
'output-charset' => $charset,
'line-length' => $lineLength,
];
$encoded = iconv_mime_encode('x-test', $value, $preferences);
return (false !== $encoded);
}

return correct answer.

Please update zend-mail package (or maybe zendframework) to fix errors.

Usually when we update zend mail it brings about tons of new bugs. We planned to release this week and don't want to hold it off again. Maybe we could change only this one function,

[dimyy]

Now I change only this function and wait results. After 3-5 days I report here test results

[dimyy]

After a week, everything is fine. No more "Subject value must be composed of printable US-ASCII or UTF-8 characters" errors. The reason is the old "canBeEncoded" function.
