Blank Characters

There are a bunch 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. Please also note, some codepoints in Unicode are marked as ignorable and often do not render anything, not even a space.
