We need, desperately and without question, two Unicode symbols for bold and italic. These are part of language and should not be an optional proprietary add on that can be skipped or deleted from text. We've been using the two "formats" to convey important information since the sixteenth century!!! It boggles my mind that we can give flesh tone to emojis, yet not mark a word as bold or italic. It makes zero sense. Especially how easy it would be to implement. It would work exactly the same way: Letters following the mark would be formatted as bold or italic until a space character or equivalent.
