Bug description:Missing info about using \p{xx} and \P{xx} escape sequences with script names.
Description:
------------
Please update documentation and add information about using \p{xx} and
\P{xx} escape sequences with script names.
From http://www.pcre.org/pcre.txt
When PCRE is built with Unicode character property support, three addi-
tional escape sequences that match characters with specific properties
are available. When not in UTF-8 mode, these sequences are of course
limited to testing characters whose codepoints are less than 256, but
they do work in this mode. The extra escape sequences are:
\p{xx} a character with the xx property
\P{xx} a character without the xx property
\X an extended Unicode sequence
The property names represented by xx above are limited to the Unicode
script names, the general category properties, "Any", which matches any
character (including newline), and some special PCRE properties
(described in the next section). Other Perl properties such as "InMu-
sicalSymbols" are not currently supported by PCRE. Note that \P{Any}
does not match any characters, so always causes a match failure.
Sets of Unicode characters are defined as belonging to certain scripts.
A character from one of these sets can be matched using a script name.
For example:
\p{Greek}
\P{Han}
Those that are not part of an identified script are lumped together as
"Common". The current list of scripts is:
Arabic, Armenian, Avestan, Balinese, Bamum, Bengali, Bopomofo, Braille,
Buginese, Buhid, Canadian_Aboriginal, Carian, Cham, Cherokee, Common,
Coptic, Cuneiform, Cypriot, Cyrillic, Deseret, Devanagari, Egyp-
tian_Hieroglyphs, Ethiopic, Georgian, Glagolitic, Gothic, Greek,
Gujarati, Gurmukhi, Han, Hangul, Hanunoo, Hebrew, Hiragana, Impe-
rial_Aramaic, Inherited, Inscriptional_Pahlavi, Inscriptional_Parthian,
Javanese, Kaithi, Kannada, Katakana, Kayah_Li, Kharoshthi, Khmer, Lao,
Latin, Lepcha, Limbu, Linear_B, Lisu, Lycian, Lydian, Malayalam,
Meetei_Mayek, Mongolian, Myanmar, New_Tai_Lue, Nko, Ogham, Old_Italic,
Old_Persian, Old_South_Arabian, Old_Turkic, Ol_Chiki, Oriya, Osmanya,
Phags_Pa, Phoenician, Rejang, Runic, Samaritan, Saurashtra, Shavian,
Sinhala, Sundanese, Syloti_Nagri, Syriac, Tagalog, Tagbanwa, Tai_Le,
Tai_Tham, Tai_Viet, Tamil, Telugu, Thaana, Thai, Tibetan, Tifinagh,
Ugaritic, Vai, Yi.
Each character has exactly one Unicode general category property, spec-
ified by a two-letter abbreviation. For compatibility with Perl, nega-
tion can be specified by including a circumflex between the opening
brace and the property name. For example, \p{^Lu} is the same as
\P{Lu}.
If only one letter is specified with \p or \P, it includes all the gen-
eral category properties that start with that letter. In this case, in
the absence of negation, the curly brackets in the escape sequence are
optional; these two examples have the same effect:
\p{L}
\pL
