Find all rows using some Unicode range (such as Cyrillic characters) with PostgreSQL?

Question

How do I find all rows of a PostgreSQL table that contain characters in some Unicode range, such as Cyrillic characters?

Answer 1

Figured it out! For Cyrillic:

SELECT * FROM "items" WHERE (title SIMILAR TO '%[\u0410-\u044f]%')

I got the range from http://symbolcodes.tlt.psu.edu/bylanguage/cyrillicchart.html. The characters have hex entities А to я, which are also my numbers above.
