So you're using Windows XP or something similarly mired in the 90s which doesn't have fonts installed with glyphs for a standard character. That's bad for you and a small number of other people but that hardly says it's not useful to the billion or so people who can read Chinese.

The nice part about having it Unicode is that if you copy and paste that character somewhere else, it'll still work. It never goes through what we used to have to deal where the same character value couldn't reliably be processed without knowing the intended encoding with certainty.
