JavaScript Regex for capitalized letters with accents

Question

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?

EDIT: like the answers already mention below, the regex above also matches some other signs, and miss some special accent characters like ý and Ý, ć and Ć and many others.

Answer 1

The range U+00C0 - U+00DC should be the uppercase equivalent for U+00E0 - U+00FC

So this text.match(/[A-Z\u00C0-\u00DC]+/); should be what you are looking for.

A site like graphemica can help you to determine the ranges you need yourself.

EDIT like the other answers already mention, this also matches some other signs.

Answer 2

Replace a-z with A-Z and \u00E0-\u00FC with \u00C0-\u00DC to match the same letters in uppercase as text.match(/[a-z\u00E0-\u00FC]+/); matches in lowercase.

However!
This is not a proper implementation, neither for lowercase nor for uppercase letters, as, for example, your lowercase match includes ÷ (division sign), which is not at all a letter, and my uppercase string will match × (multiplication sign), which looks like an X, but isn't actually a letter either.
In addition to that, you're missing characters like ý and Ý, ć and Ć and many, many others.
