Unicode v1.5.0 Unicode.GeneralCategory.Derived View Source
For certain operations and transformations (especially in Unicode Sets) there is an expectation that certain derived general categories exists even though they are not defined in the unicode character database.
These categories are:
:any
which is the full unicode character range0x0..0x10ffff
:assigned
which is the set of codepoints that are assigned and which is therefore equivalent to:any
-:Cn
. In fact that is exactly how it is calculated usingunicode_set
and the results are statically copied here so that there is no mutual dependency.:ascii
which is the range for the US ASCII character set of0x0..0x7f
In addition there are derived categories not part of the Unicode specification that support additional use cases. These include:
Categories related to recognising quotation marks. See the module
Unicode.Category.QuoteMarks
.:printable:
which implements the same semantics asString.printable?/1
:visible:
which includes characters from the[[:L:][:N:][:M:][:P:][:S:][:Zs:]]
set
