Template:Chset-color-misc/doc

Usage
Used with Template:chset-tableformat data rows for characters in the M*, Z* or C* Unicode categories, i.e. whitespace, combining characters, control characters and end-user defined characters.

Note that Private Use Area characters are classified as Co, but private use mappings in individual encodings may be for well-defined characters which do (or did) not have Unicode codepoints (e.g. in KPS 9566), it may make more sense to assign those to a hypothetical category for that character. If a private use mapping is for user definition, then they should be coloured as Co.
