In my old mirc version 6.03 I can use nicknames as an example nicknames with the letter Ñ
example ; nickname; niño or español

* Your nick is now niño << in status
* Drem is now known as niño << in channel
* Your nick is now español << in status
* niño is now known as español << in channel

I downloaded the mirc v7.61 and it won't let me use nicknames so niño or español in the status I get this error:
[12:43] niño Erroneous Nickname
some way or some way to fix it please ??? either configurations, it is just mirc since the ircd supports clear example is above
