I came across some regular expressions that contain [^\\p{L}]. I understand that this is using some form of a Unicode category, but when I checked the documentation, I found only the following “L” categories:

Lu  Uppercase letter    UPPERCASE_LETTER
Ll  Lowercase letter    LOWERCASE_LETTER
Lt  Titlecase letter    TITLECASE_LETTER
Lm  Modifier letter     MODIFIER_LETTER
Lo  Other letter        OTHER_LETTER

What is L in this context?

    Taken from this link: http://www.regular-expressions.info/unicode.html

    Check the Unicode Character Properties section.

    \p{L} matches a single code point in
    the category “letter”. If your input
    string is à encoded as U+0061 U+0300,
    it matches a without the accent. If
    the input is à encoded as U+00E0, it
    matches à with the accent. The reason
    is that both the code points U+0061
    (a) and U+00E0 (à) are in the category
    “letter”, while U+0300 is in the
    category “mark”.
