Blank Characters

There are a lot of white-space character in Unicode. Sometimes, such blank codepoints have a totally different meaning, but as a side-effect, they also do not contain any glyph. The following list collects characters which might render no glyph. The exact behavior depends on the platform/operating system.

Also see Ignorables for the current list of codepoints in Unicode marked as default ignorable codepoints, which often do not render anything.
