Breakline <br /> and or Un-linebreak-able Space

[Jose Amaral Rego]

What would be the problem in using &nbsp; instead of <br />. It does not seem to cause problems with styling, other then what it is mention in link below. I do not have netscape, opera or any other browsers except ie/ff. It seem to pass validation or is that temporary.

Have not tested these out yet.

soft hyphen ­
en space   
em space   
thin space

&nbps; is a non-breaking space.
And <br /> is a break to new line.

They're totally different.
