JavaScript Regex for capitalized letters with accents

In JavaScript, its easy to match letters and accents with this regex:

text.match(/[a-z\u00E0-\u00FC]+/i);

And only the lowercase letters and accents without the i option:

text.match(/[a-z\u00E0-\u00FC]+/);

But what is the correct regular expression to match only capitalized letters and accents?
