Character not rendering as it should
I'm running OS X 10.9.2 on my MacBook Air and I'm having problems inserting a particular character into documents. In Character Viewer, it is U+2263, "STRICTLY EQUIVALENT TO", and it displays as three horizontal, parallel lines. However, when I insert the character into any document (including this post), I get this: ≣ (four parallel lines). I've tried the various Unicode fonts I have installed, but it won't budge from Menlo Regular.
Any tips on how to use the glyph that displays in Character Viewer would be much appreciated. Thanks.
Best,
