To answer that part: no, UTF-8 vs ISO-8859-1 makes no difference to
that symbol, because it's part of the ASCII range, which is shared
between all of the character encodings supported by Cygwin.

They do you have some mouse support actually. Enable with ':set
mouse=a' in vim, and with Alt+m in nano.

That one won't work, because UTF-16 is not ASCII-compatible.
