[antlr-interest] '–' versus '-'

[ian eyberg]

hi everyone,

  just ran across a problem which I hope
someone knows the answer to.

I thought I was trying to parse out a '-'
but on closer examination I need to parse
out a '–'.

looking that up one is called a en dash and the latter
is an em dash.

I tried to throw it into a lexer and a parser rule
to no avail -- do I need to separate this into hex
somehow? How do you guys deal with these?

Thanks,

-Ian
