According to the documentation of java.util.Pattern, the POSIX character class \p{Graph} ([:graph:] in POSIX notation) matches "a visible character: [\p{Alnum}\p{Punct}]". However, this is limited to ASCII characters only. Is there an equivalent class or expression for matching (visible) Unicode characters?

1According to the Unicode Regular Expressions standard, this expression means "anything other than a separator and a control character." http://www.unicode.org/reports/tr18/#Categories

Yep. And if it ain't one of them, it's visible.
