I'm not fluent, but how so? The 。or ，or 、seem fine when centred. The《 and 》 or 「 and 」get rotated and also look fine. The bigger issue is Arabic numerals, and mixed case or long Latin alphabet words.

I always thought bracket quotes looked exactly like what they are, a container for words: https://i.imgur.com/IlwSjnZ.png https://i.imgur.com/IlwSjnZ.png -- For example, this sentence is written in "vertical Chinese".
