using raw 'ꯍ', i can cause a character entity to appear in the output, but when i use raw with an attribute, the value's representation will land outside of the tag (and only the attribute name, not its value is printed).
i think it would be most intuitive to make it so that T.div 'x-foo': 'ꯍ' renders as <div x-foo="ꯍ"></div>.
are there any workarounds?
