Template:Unichar/gc/doc

Overview
This subtemplate returns Unicode General Category (gc)  for special code points (like, space characters, formatting characters). When regular gc like Letter, Symbol, Mark, or Punctuation, it returns a blank.

Parameters
This is a subtemplate, so parameters may have tight requirements. Input: (unnamed)

The code point value is required as a decimal value, because we are using the  numerical calculations.

For five Arabic number markings U+0600 – U+0603 and U+60DD, it returns. While Cf formatting characters usually have no glyph, these five have. By adding the "(visible)" text, these characters are shown (while regular Cf characters are hidden).
