Source string: {{{ public 'subject' => string '=?utf-8?B?V3VzaHUgaW5mb3JtIC0gU2FjZW5zaWJhcyBJZ2F1bmk=?= =?utf-8?B?amEgKFRhbGxpbmEpLCDRgdC+0YDQtdCy0L3QvtCy0LDQvdC40Y8g0LIg0KLQsNC7?= =?utf-8?B?0LvQuNC90LUgMTEg0LTQtdC60LDQsdGA0Y8=?=' (length=182) }}} where spaces between =?...?= lines are actually tabs, results to {{{ array 0 => object(stdClass)[54] public 'charset' => string 'utf-8' (length=5) public 'text' => string 'Wushu inform - Sacensibas Igauni' (length=32) 1 => object(stdClass)[53] public 'charset' => string 'default' (length=7) public 'text' => string ' ' (length=1) 2 => object(stdClass)[55] public 'charset' => string 'utf-8' (length=5) public 'text' => string 'ja (Tallina), соревнования в Тал' (length=48) 3 => object(stdClass)[56] public 'charset' => string 'default' (length=7) public 'text' => string ' ' (length=1) 4 => object(stdClass)[57] public 'charset' => string 'utf-8' (length=5) public 'text' => string 'лине 11 декабря' (length=26) }}} This produces: {{{ Wushu inform - Sacensibas Igauni ja (Tallina), соревнования в Тал лине 11 декабря }}} with unwanted spaces in words "Igauni ja" and "Тал лине".
