Block Escapes

A block escape is a simple way to refer to a range of characters that have some property in common. Each block escape has a name; to use a block name, prepend Is to it. Block escapes are used with the \p and \P operators. For example, the expression \p{IsThai} refers to the Thai characters (&#x0E00 – &#x0E7F). The expression \P{IsThai} refers to everything except Thai characters. The block names are listed here in the format defined in the XML Schema spec.

Table E-1 shows the complete list of block escapes. This table was generated from version 5.0.0 of the file blocks.txt. The list of block escape names is part of the Unicode Character Database; see http://www.unicode.org/ for the latest version of the Unicode standard.
