unicode bug?

[Derick Eddington]

The external representation is using escaping for some of the characters. Bug? Or, is this because these are modifier code-points (or whatever they're called) that don't have glyphs of their own? and does the display show it the same because my terminal or font-system knows how to render the modifier code-points?

The issue is still open for symbols though.

Fixed for symbols in 1584.

I am getting this in Cygwin. It seems Cygwin does not have a 'locale' command, so I used 'chcp' from windows. I am not sure if this is a Cygwin bug.

Here is a better solution to the Cygwin UTF-8 issues.
