Unified Braille
In all braille systems, the braille pattern dots-0 is used to represent a space or the lack of content.[1] In particular some fonts display the character as a fixed-width blank. However, the Unicode standard explicitly states that it does not act as a space,[2] a statement added in response to a comment that it should be treated as a space.[3]
Plus dots 7 and 8
Related to Braille pattern dots-0 are Braille patterns 7, 8, and 78, which are used in 8-dot braille systems, such as Gardner-Salinas and Luxembourgish Braille.
