Text within guillemets (angle quotes) is unsearchable (2.3)

Text surrounded with characters « (00AB) and » (00BB) cannot be found with search, unless "search inside words" is enabled. They are treated like word letters.

This is in contrast with behavior of regular single ' and double " quotes, which are not considered as letters by CN.
