Summary

Retrieves a Unicode Character Database (UCD )character property of a Unicode codepoint.

Description

Use the codepointProperty function to retrieve a UCD property of a Unicode codepoint.

The Unicode standard and the associated Unicode Character Database (UCD) define a series of properties for each codepoint in the Unicode standard.

note

This function is not intended for general-purpose use; please use functions such as toUpper or the equals operators instead.
