B⃦ sucks extra hard for being 2 chars (we invented new problems for you!)
B⃦ is itself a single character, even if comprised of two codepoints.
It's also the same character the forum is using a webfont to render in
BTC.
Using multiple codepoints for a single character is
not new.
How many times do you need to see posts from others saying (and even showing) that it isn't displaying for the majority of people as it does for you?
Are you using UTF-16 instead of UTF-8?
Have you successfully rendered this symbol on a system using UTF-8?
Have you viewed this symbol on any system other than your own?
I'm guessing your answers will be: infinity, yes, no and no, respectively.
