Return the length of an individual Char.
Determine whether the given Char is “wide”, that is, whether it spans 2 columns instead of one.
Determine whether the given Char is “zero-width”, that is, whether it has no visible representation and does not advance the cursor position. This includes control characters and certain Unicode zero-width characters.
