Any Uppercase Letter

\u finds any uppercase letter. This covers all Unicode characters that can be considered letters, such as all Latin letters with accents, Cyrillic, Hebrew, and Arabic letters. I’ll reintroduce our “one or more” operator, +, from page 6, as it gives more sense to the wildcards outlined in this section. \u+ means “find at least one uppercase letter.” When you try it, you’ll see that InDesign finds any sequence of one or more capital letters, so this simple expression is useful for finding acronyms and other abbreviations. But it also finds single-letter words such as A and I, so use \u\u+ to find words of two or more capitals.
