Expand description

Enumerated property General_Category.

General_Category specifies the most general classification of a code point, usually determined based on the primary characteristic of the assigned character. For example, is the character a letter, a mark, a number, punctuation, or a symbol, and if so, of what type?

GeneralCategory only supports specific subcategories (eg UppercaseLetter). It does not support grouped categories (eg Letter). For grouped categories, use GeneralCategoryGroup.
