[char-set1 & [char-set2]]		Character set intersection. Matches all characters in
		char-set1that are also in char-set2. For ex-
		ample, [\x{0}-\x{7f}&[\p{L}]]matches all letters
		between 0 and 127.
\x{hhhh}		Matches up to 31-bit Unicode hexadecimal charac-
		ter specified by hhhh.
\p{UnicodeCategorySpec]		(Only valid in character set) Matches characters in
		UnicodeCategorySpec. Where UnicodeCat-
		egorySpec uses the standard general categories
		specified by the Unicode consortium. For example,
		[\p{L}] matches all letters. [\p{Lu}] matches all up-
		percase letters. See Unicode Category Specifica-
		tions for Regular Expressions.
\P{UnicodeCategorySpec]		(Only valid in character set) Matches characters not
		in UnicodeCategorySpec. For example, [\P{L}]
		matches all characters that are not letters. This is
		equivalent to [^\p{L}]. [\P{Lu}] matches all charac-
		ters that are not uppercase letters. See Unicode
		Category Specifications for Regular Expressions.
\p{UnicodeIsBlockSpec]		(Only valid in character set) Matches characters in
		UnicodeIsBlockSpec. Where UnicodeIsB-
		lockSpec one of the standard character blocks
		specified by the Unicode consortium. For example,
		[\p{isGreek}] matches Unicode characters in the
		Greek block. See Unicode Character Blocks for
		Regular Expressions.
\P{UnicodeIsBlockSpec]		(Only valid in character set) Matches characters not
		in UnicodeIsBlockSpec. For example,
		[\P{isGreek}] matches all characters that are not in
		the Unicode Greek block. This is equivalent to
		[^\p{isGreek}]. See Unicode Character Blocks for
		Regular Expressions.
