Hi guys and thanks for the great project!

I've added a couple of API methods, review them please. Comments are welcome.

Thanks,
Denis.

using importContacts with non-latin first or last name causes 404 error :(
how can i fix that?

[denistex]

Hi @FragsterAt,

It looks like request with non-latin characters constructed incorrectly, so the server returns 404. I think good points to start research are following:

• String serialization methods in telegram-tl-node: writeString, _writeBytes.
• Encryption methods in telegram-mt-node: serialize.

Hope this helps.

@denis-it At first glance, this solves the problem:

// Write the `string` value given as argument
TypeObject.prototype.writeString = function (str) {
    //return this.writeBytes(str);
    return this.writeBytes(Buffer.from(str));
};

you can use it same way in https://github.com/goodmind/telegram-mtproto and https://github.com/zerobias/telegram-mtproto if they're buggy. I can not check, because I can't call importContacts with any arguments: zerobias/telegram-mtproto#6

I've checked it, working fine with Buffer.from(str). Good work, @FragsterAt! 👍
