Some minimal amount of folding will nevertheless be necessary even in asymmetric mode, in order to find character sequences produced by decomposing characters like ö into o and the combining mark ̈. That's because these two characters when juxtaposed (ö) look identical to the precomposed character on most displays, so we should by default find such decomposed sequences even when the search string includes the precomposed character.
