How do I make the player accept the name of multilingualism UTF-8 encoding ?

[Castillo]

I don't understand your question, can you explain yourself better?

[abu5lf]

How do I get player's name appears in a different language?

[Castillo]

If you want to translate player name to another language, then I don't know if it's possible.

[abu5lf]

Why ؟ are some servers have it !

[Castillo]

You can ask them how they'd it maybe.

I think he means how to make different kind of letters show correctly, like having your nick in Chinese letters.

MTA does not allow it, you need to script it on another way and pls remove that annoying smilley ... I seriously don't like it, to see people crying when they are not........

You can use outputchatbox

  
function chat(text, msgtype) 
local root = getRootElement() 
local name = getPlayerName(source) 
cancelEvent(true) 
outputChatBox("#0066FF" .. name .. ":#0066FF " .. text, root, 255, 255, 255, true) 
  
end 
addEventHandler("onPlayerChat", root, chat) 
  

You have to do the rest of the script and I think you have to work with elementdata.
