Unicode code page and ☃.net

Hi,
I have a question regarding the supported Unicode code page. I thought
once you have unicode code page loaded, all glyph or character should be
able to map and display correctly regardless of which OS or language you
are using?

However, i have this snowman: ☃

but once i input www.☃.net into the URL field, the snowman displays empty.
 Does anyone know if this is result in unicode fonts that isn't used
correctly?

This is also applicable if i enter the following Chinese character in
Japanese OS: 橠徇欯幜.NET

Does anyone know why the empty string is showing?
thanks
