PHP: posting to Twitter, the signature calculation

Built into the website authentication via Twitter (using a library Twitter-async from Jaisen Mathai), now I want that when the user change the profile on the website automatic post to your Twitter message.

But there is the problem: Russian messages are simply not sent. More precisely, the problem is (as I understand it) that incorrectly calculates the request signature. Googled — many have the same problem, all nod in the direction of UTF-8 characters.

Looked at the source code of the library, but there is, in theory, everything is normal, each parameter is processed so:
public function encode($string)
 return rawurlencode(utf8_encode($string));

Also, I tried to replace:
public function encode($string)
 return rawurlencode(iconv('windows-1251', 'UTF-8', $string));

also did not help. I've tried other libraries (in particular TmhOAuth by Matt Harris) — the situation is completely analogous.

If it matters, the library was built in Kohana 3.2

Where to dig, where can be the problem?

Use this Bible, Russian language approx. I always Unicode.

Regular library Kohana tried? The same OAuth should work.

the length of the message as checked? my records were in utf-8, the result was incorrectly calculated length of the message, the message exceed the limit, and was not published
The length of the message is verified by the server of Twitter and it is already in excess returns the appropriate error - Jessik commented on October 8th 19 at 00:46
and at the moment what error is returned? - clementine_Trembl commented on October 8th 19 at 00:49
the use twitteroauth by Abraham Williams. Don't have any problems - clementine_Trembl commented on October 8th 19 at 00:52
dali, not being able to authenticate the OAuth request. In running the app on the Twitter website there is a tool that allows you to generate a test signature request. So with this tool I just found out that the problem is in the request signature OAuth_signature: for the English tweets, the library calculates it correctly, and for Russian the signature turns out wrong.

Russian-language tweets sent through it? - Jessik commented on October 8th 19 at 00:55
And, by the way, I tried, and this library too — did not help. - Jessik commented on October 8th 19 at 00:58
Yes, tweets are sent only in Russian. Working since last may, almost a year already. This uses the twitteroauth OAuth library, and your library also use OAuth? Can updated the library, and it is something wrong, old versions work, and the new no longer. - clementine_Trembl commented on October 8th 19 at 01:01
dali, can you give the code that you are using? - Jessik commented on October 8th 19 at 01:04
Yes, all my libraries use OAuth - Jessik commented on October 8th 19 at 01:07

1. PHP version?
2. Installed mb_string extension
If PHP < 5.3.10 is mb_string use for counting long UTF-8 string mb_strlen instead of strlen (proof)
seems fixed in 5.4.

XS has a version with github (Twitter-async from Jaisen Mathai) — the test worked:!/jmathai_test/status/190858746497470464
