I tried some examples and found it weird to have U+0020 in between two
fullwidth Latin characters. I'll be interested in seeing a real world
example and its use case. Perhaps I am missing something.

I sent this to Japanese ML too where I got one feedback: if text-transform:fullwidth does affect U+0020, would it run first or would white space processing[1] run first?

I assume white space processing runs first, but we should probably add this to the spec to make it clear.

The question came up during the test case development/review[1] for text-transform:fullwidth[2].

Unicode defines U+3000 IDEOGRAPHIC SPACE is the full-width counterpart of U+0020 SPACE, so I guess it should be done. The primary use case for the property value is to typeset Latin characters and digits like ideographic characters as written in the spec, so transforming U+0020 to U+3000 makes sense to me given the use case.

But U+0020 is a little special in HTML/CSS and therefore I'd like to confirm if doing so doesn't harm anything badly.

Any opinions appreciated.
