Problem adding Albums with greek characters from both database and filesystem

[ghost]

I have lots of albums with greek characters on both tags and filenames/directories. All of them appear in filesystem and database views but the options "Append to queue/Replace queue/Add to playlist" menu
never appears on them if I click on the album cover in database view or on the cross symbol in filesystem view.

I don't know if it happens with other languages too. I can only test with Greek.

The myMPD version I use is 4.2.1.

Error message:

If i click on then song name, the song added successfully in the queue.
From Menu at the left, it throws the error i mention. Even in the queue(if i added it through click on the name as i mention) i cannot remove the song if i wanted to, because when i click on the "+", throws the same error.

Can you test it with non-minified files and post the error here?

One is at line 1716, which is this function:
function addMenuItem(href, text) {
return '<a class="dropdown-item" href="#" data-href='' + btoa(JSON.stringify(href)) + ''>' + text +'';
}

The other is 1743 line:
menu += addMenuItem({"cmd": "appendQueue", "options": [type, uri, name]}, 'Append to queue') +

and the other is 434 line:
else if (event.target.nodeName == 'A') {
showMenu(event.target, event);
}

It seems it is a unicode problem of base44 encode and decode: https://developer.mozilla.org/en-US/docs/Web/API/WindowBase64/Base64_encoding_and_decoding

I implemented the solution 1 in linked document in the devel branch. Can you please test it?

Case closed. One more annoying bug goes down.

Thanx JC. Great work.
