I'd agree this should be refactored when another use case crops up.

On all other modes, hitting a hard line break resets the UBA to the state at the beginning of the current block, but when in Unicode: plaintext mode, we recalculate the direction of this new paragraph and set the status to an embedding level of 0/1 depending on the first character with strong directionality.
