+1 from me.

Cannot reproduce this right now.
I had a lot of various problems with Polish Latin-2 ISO-8859-2
characters, but to be honest these were in pre-UTF era.

There is no output from META tag. So, no.

But, w3c html-markup syntax documentation says:

"end tags consist of the following parts, in exactly the following order:

    A "<" character.
    A "/" character
    The element’s tag name.
    Optionally, one or more space characters.
    A ">" character.
"

They don't mention any newline character.

It shouldn't.
Meta tag can only have two attributes. There is no reason to concatenate
anything else.

I agree. But code really should be valid and IMHO little improvements
and code cleanups are ok.
