Transaction sign fails when using not-latin symbols in title or body

[norbis]

Hi, trying send post to blockchain and transaction sign fail when using non-latin chars in title or body. This code works:

    $strPermlink = '...Post perm link...';
    $strAuthor = '...Account...';
    $strPostingWif = '...Private posting wif...';
    $strMainTag = '...Main tag...';
    $connector = new GolosWSConnector();
    $answer = OpComment::doSynchronous(
        $connector,
        $strPostingWif,
        $strAuthor,
        $strPermlink,
        'Post test title',
        'Post test body',
        json_encode([
            'tags' => ['golos'],
            'format' => 'markdown',
        ]),
        $strMainTag,
        ''
    );

But this code not works:

    $strPermlink = '...Post perm link...';
    $strAuthor = '...Account...';
    $strPostingWif = '...Private posting wif...';
    $strMainTag = '...Main tag...';
    $connector = new GolosWSConnector();
    $answer = OpComment::doSynchronous(
        $connector,
        $strPostingWif,
        $strAuthor,
        $strPermlink,
        'Русский',
        'Post test body',
        json_encode([
            'tags' => ['golos'],
            'format' => 'markdown',
        ]),
        $strMainTag,
        ''
    );

With error: "3030000 tx_missing_posting_auth: missing required posting authority"
