No matches found using ytsearch with query including special characters

[Hydro001]

Description

Hi,

When using ytsearch with a query containing "é" or "à" or any "special" character, for exemple Annonces de Macron détaillées, députés accusés, trésor à 17 milliards d'€... Actus du jour, i get : No matches found and when looking at the request it replaces "é" with "Θ" for exemple, it replaces other special characters with other things too.

Error :

2022-06-25 23:58:07.312  INFO 13696 --- [  XNIO-1 task-1] l.server.player.AudioLoaderRestHandler   : Got request to load for identifier "ytsearch:Hugo DΘcrypte - Annonces de Macron dΘtaillΘes, dΘputΘs accusΘs, trΘsor α 17 milliards d'Ç... Actus du jour"

Works on my side, Shoukaku properly serializes search queries using URLSearchParams, so this is either a lavalink issue, or an encoding issue on your side(?)

I'll try again with a fresh project and update the issue it it still isn't working, Though i have one question, why does lavalink replaces the special characters when outputing in the console ?

[Deivu]

It's kinda an issue in Java programs when the encoding is not properly set to UTF8. I remember having this similar issue on my Java project (which is not Lavalink) way before

[Hydro001]

I have the following code which is in Node.js :

const Discord = require('discord.js');
const { Shoukaku, Connectors } = require('shoukaku');
const config = require('./config.json');
const Nodes = [{
    name: config.lavalink_name,
    url: `${config.lavalink_url}:${config.lavalink_port}`,
    auth: config.lavalink_auth
}];

const client = new Discord.Client({ 
    intents: [Discord.Intents.FLAGS.GUILDS, Discord.Intents.FLAGS.GUILD_MESSAGES, Discord.Intents.FLAGS.GUILD_MESSAGE_REACTIONS, Discord.Intents.FLAGS.GUILD_VOICE_STATES, Discord.Intents.FLAGS.GUILD_INTEGRATIONS ],
    partials: ['MESSAGE', 'CHANNEL', 'REACTION'],
});
const shoukaku = new Shoukaku(new Connectors.DiscordJS(client), Nodes);

shoukaku.on('error', (_, error) => console.error(error));

client.on('ready', () => {
    console.log('Bot ready !');
});

client.on('messageCreate', async (message) => {
    const node = shoukaku.getNode();
    if (!node) return;
    const result = await node.rest.resolve(`ytsearch:"Annonces de Macron détaillées, députés accusés, trésor à 17 milliards d'€... Actus du jour"`);
});

client.login(config.bot_token);

And i get on the lavalink side :

2022-06-26 13:18:34.297  INFO 2096 --- [  XNIO-1 task-1] lavalink.server.io.SocketServer          : Connection successfully established from shoukakubot/3.1.2 (https://github.com/Deivu/Shoukaku)

2022-06-26 13:18:51.568  INFO 2096 --- [ader-2-thread-1] lavalink.server.player.AudioLoader       : No matches found

Using the latest version of Shoukaku which is 3.1.2 i believe.

I even opened an issue on both lavalink and lavaplayer and they said that it would come from the client i use which is Shoukaku, i even tried other clients (Poru) and it did the same.

And i finnaly did a request using Axios on the loadtracks endpoint and it shows me the same.

I'm honestly kinda lost on this and don't know how to solve the issue, lavalink says that the issue comes from the clients used and the clients says that it probably comes from Lavalink so i don't know what to do.

[Deivu]

I think this is an issue with your Lavalink and your server most likely, I don't do any modification on the raw query you pass to Shoukaku. Infact the reason why you do ytsearch:query now in v3 is to signify that what you pass here is on 1:1 ratio on what Lavalink receives. Nothing is modified. Now it means its very likely the Lavalink you are using is the one causing issues here. Now on your topic on why the Lavalink logs looks different on your query is because your Lavalink can't show the special character.

[Hydro001]

Can you give me the Lavalink version your using, just to try, because if it still isn't working with the one you use it really means that the issue comes from me and not from lavalink or any clients.

Thank you

I can't remember if I built this or I downloaded this but here is what I use in my dev enviroment

I found this version on the ci server but the jar doesn't seem to be there anymore, could you send me your jar ? Or tell me how you built it by yourself, never used gradle or maven.

Sorry for asking dumb stuff

[Deivu]

Clone the repo, call gradlew build or ./gradlew build depending on system

[Hydro001]

I did but i get :

[Deivu]

Most of that could be fixed by googling, while I do give support for Lavalink, this is not the place for that. Since this already not involves the library Shoukaku. Try asking on my server OR lavalink server for that

[Hydro001]

I understand, i will join your discord server and ask there then, thanks 👍
