You can't find them? Did you look? Googling `regex \\pL` leads directly to this: http://www.regular-expressions.info/unicode.html – germi Apr 17 '14 at 13:59

\\pL is a Unicode property shortcut. It can also be written as as\p{L} or \p{Letter}. It matches any kind of letter from any language.

\\pL is a shorthand for \\p{L}
In addition to the standard notation, \p{L}, Java, PHP, Perl, PCRE and the JGsoft engine allow you to use the shorthand \pL. The shorthand only works with single-letter Unicode properties. \pLl is not the equivalent of \p{Ll}. It is the equivalent of \p{L}l which matches Al or àl or any Unicode letter followed by a literal l.
