Dear Monks,

I need to write simple regular expressions such as "any word in all capital letters that is longer than 2 characters", which I would write as

/\b\U/w{2,}\E\b\/

This needs to work in Unicode (UTF8) also, and after glancing at perlretut, perlunicode etc I still have a number of questions:

- does \b work with Unicode "words"?
- what's the difference between \p{Lu}, \p{IsUpper} (if there is one)
- How would I rewrite the above regexp? Is this correct:

/\b\p{Lu}{2,}\b\/
I assume I don't need to use (\w\p{Lu}), since \w should be a subset of \p{Lu}?
