Possible issue with Twitter glyph and the f301 code point in some browsers

[Otto42]

Issue reported here:
https://meta.trac.wordpress.org/ticket/3352

On the dashicons resource page, the "Copy Glyph" function doesn't work properly in some browsers, but only for the f301 code point (the Twitter icon).

I have no explanation for this, but perhaps f301 is being used for something else or is interpreted differently, somehow?

There are some explanations on the meta ticket now:
