Ideally the resulting IRI would use a normalized form, such as Unicode Normalization Form C (NFC, [UTR15]), since that ensures a stable, consistent representation that is most likely to produce the intended results. Implementers and users are cautioned that, while denormalized character sequences are valid, they might be difficult for other users or processes to guess and might produce unexpected results.

In particular, I think this matches what implementations actually do.
