In english, it has no accepted usage in formal writing, but it may occasionally be used for a few different reasons in informal writing. It can also be used to show approximation, e.g. A mark ˜ placed especially over the letter n (as in spanish señor sir) to denote the sound \nʸ\ or over vowels (as in portuguese irmã sister) to indicate nasality.
