Sometimes adding a blank character helps with formatting. For example on Lemmy, it helps me separate lines of text if I insert a blank character between other lines. Currently, do that by copy-and-pasting the blank character from elsewhere. Here is an example
Is there a way I can do this on Linux easily from the keyboard? I am using KDE Neon and have the compose key enabled so that I can easily type uncommon characters like ‽, ñ, and é easily.
Yes, but it mostly depends how it’s interpreted by a given program. Some will interpret it as a character being there, but it may take up no space on the screen, for example. Some will show a space, but won’t count it as a space character so it can bypass some text restrictions. Some may show different spacing. Many will also simply not accept them as valid characters.
