E-Mail with UTF encoded Subject - if longer then expected length => becomes garbled in gmail - El Forum - 06-11-2009

Hi,
I dont want to yell "BUG!!!" just because I have encountered this unexpected behavior BUT I noticed that email subjects with non-english characters (cyrillic) end up showing as "=d0=97=d0=95=d0" when they are longer then a certain length.
I was able to fix it by making 2 modifications to Email Class -> function _prep_q_encoding
Modifications (2):

Code:
for ($i = 0, $length = strlen($str); $i < $length; $i++)

        {

            // Grab the next character

            $char = substr($str, $i, 1);

            $ascii = ord($char);

            // convert ALL non-printable ASCII characters and our specials

            if ($ascii < 32 OR $ascii > 126 OR in_array($char, $convert))

            {

commented out this =>        //$char = '='.dechex($ascii); 

            }

            // handle regular spaces a bit more compactly than =20

            if ($ascii == 32)

            {

and commented out this =>    //$char = '_';

            }

            // If we're at the character limit, add the line to the output,

            // reset our temp variable, and keep on chuggin'

            if ((strlen($temp) + strlen($char)) >= $limit)

            {

                $output .= $temp.$this->crlf;

                $temp = '';

            }

            // Add the character to our temporary line

            $temp .= $char;

        }

Here are my headers
With 'bad' email subject:

Subject: =?utf-8?Q?Objava: =d0=97=d0=95=d0=9c=d0=af =d0=a1=d0=9c=d0=95=d0=9b=d0?=
=?utf-8?Q?=9d=d0=98=d0=a6=d0=90?=

With 'fixed' email subject:

Subject: =?utf-8?Q?Objava: ÐÐÐÐ¯ Ð¡ÐÐÐÐÐÐ¦Ð?=

Can someone comment on this
Is this a bug?
May I have other issues by commenting out those sections of the class (mentioned above)?

Same issue for me, thanks for the trick.

Thanks!
This really saved my time :-)

I commented out also this line:

$str = trim(preg_replace('/^(.*)$/m', ' =?'.$this->charset.'?Q?$1?=', $str));

After that, I got this:

Subject: MY_TEXT_IN_JAPANESE

instead of this:

Subject: =?utf-8?Q?MY_TEXT_IN_JAPANESE?=
