My digital version of《现代汉语规范词典》seems to be using halfwidth ideographic commas, 、
(U+FF64).
Here's their definition for 巾:
名 用来擦、包或盖东西的小块织物
It looks like a poor attempt at a fullwidth ideographic comma (顿号) and seems to be missing any sort of space what-so-ever after the punctuation mark.
Is there ever usage of the halfwidth ideographic comma in Chinese punctuation? (Add your own spaces?)
