Key

The Categories are from UCD Table 8. Property Summary Table, with some extended categories: Emoji, IDNA, Regex, Security, and UCA.

The Datatypes are from UCD Table 5. Property Type Key.

The Sources are:

UCD - Unicode Character Database
Unicode - The Unicode Standard. For example, isLowercase or toNFC
UTS - a Unicode Technical Standard. For example, identifier-restriction is from UTS #39, and alnum from UTS #18.
X-ICU - from ICU: Typically a derived property, such as Case Sensitive.
X-Demo - properties purely for demonstration purposes.

Fonts and Display. If you don't have a good set of Unicode fonts (and modern browser), you may not be able to read some of the characters. Some suggested fonts that you can add for coverage are: Noto Fonts site, Unicode Fonts for Ancient Scripts, Large, multi-script Unicode fonts. See also: Unicode Display Problems.
