As you know, the “Normal space character (U+0020)” itself is invisible, and there are many other characters that are also “invisible” like this space character. These characters are designed for various functions, mainly for “Spacing”, either vertical or horizontal spacing.

What I use for this generator is precisely one of these kinds of characters. I use the “Hangul filler character”. It is a space character for ‘Hangul Typing‘.

It’s a universally recognized character. It’s safe to use in everything from online to offline.

There is other character that you can use, that are “invisible”, like this Hangul Filler, for example Zero Width Space (U+200B), and etc. Here the list of this type of character.

And there is a bunch more, according to Wikipedia. So yeah, you have many options to use when you want to prank your friend with a blank message or blank comment. Then again, I haven’t tried it all. So yeah, some social media probably recognize them as space and won’t allow you to create blank message prank with it.
