Code in the platform directory depend on anything outside the platform directory, so clearly this not the right place for these definitions. They also have nothing to do with the DOM text node. Perhaps you meant for this to move somewhere in platform/text?

I meant “should not depend”.

You're right, I'll find another place for it.

This is the wrong place for these. These should be somewhere in the platform directory or in WTF since they are used by things like FontCascade.  Maybe in TextBoundaries.h? Maybe wtf/unicode/CharacterNames.h? Maybe a new file.

This is a layering violation.
