Unicode Character Blocks for Regular Expressions
The Unicode consortium standard regular expression block categories are supported. The syntax for spe-
cifying a character block is:
\p{IsBlockName}
The above syntax matches the characters in the block specified. The following syntax matches all charac-
ters not in the block specified:
\P{IsBlockName}
The \p and \P notations may only be used inside a character set specification. For example,
[\p{isBasicLatin}] matches all characters in the Greek block. [\P{isBasicLatin}] matches all characters
that are not in the Greek block.
The following is a list of the non-standard valid character block names. This list was generated from XML
standards found at the World Wide Web Consortium Web site (http://www.w3c.org).
• XMLNameStartChar - All characters that are valid for the start of an XML tag name.
