title: Is there a Unicode equivalent for `{\pGraph}` in Java / POSIX regular expressions?
body: <p>According to the documentation of <a href="http://java.sun.com/javase/6/docs/api/java/util/regex/Pattern.html" rel="nofollow noreferrer">java.util.Pattern</a>, the POSIX character class <code>\p{Graph}</code> (<code>[:graph:]</code> in POSIX notation) matches <em>"a visible character: <code>[\p{Alnum}\p{Punct}]</code>"</em>. However, this is limited to ASCII characters only. Is there an equivalent class or expression for matching (visible) Unicode characters?</p>
