A while ago, I came across someone using emoji as a Wi-Fi network name (SSID), I tried to do the same on my wifi router (I wanted the delightful smiling poo emoji 💩) but my router, sadly wouldn’t let me.
I saw it again the other day, and I thought I’d have another try, after all this was years ago and I have a much newer router, and newer version of DD-WRT running on it.
But, I was rudely told that what I was trying to do was illegal.
Not to be deterred, I thought I’d try changing it via SSH… but that was not to be either.
Inserting the emoji returned “p)” which was not accepted, I did also try the unicode char for it “U+1F4A9” but that didn’t work either.
Turning to google, I wondered if anyone had done this successfully before, but all I could find was this article, This was done on the same model of wireless router as I own, but using the stock firmware.
But it did give me a good idea… So taking the same approach as in the article, but skipping straight to the server-side method, I used chrome dev tools to inspect the request;
So that is all well and good, but I need to replicate the request with new parameters, so turning to postman
Fingers crossed, I hit send on the request… and low and behold!
So far I’ve not had any issues with modern-ish devices finding/connecting to it, however I did leave the 2.4ghz radio of my wireless router alone, so that older devices can use it if need be.
