What should be done with this file(s)?

Is the sms emoji reception problem still actual on cssu?

During 10 years with my N900, I thought I didn't have friends using emojis... but actually I might have lost all of them by not answering their not received messages

So, to correct this and keep the few remaining friends, what should be done now?

I tried to follow instructions but a lot of 404 appeared as the subject is quiet old...
