transform_utf8(path, fun, dry)

`path`	A vector with file paths to transform.
`fun`	A function that returns a character vector.
`dry`	To indicate whether styler should run in dry mode, i.e. refrain from writing back to files .`"on"` and `"fail"` both don't write back, the latter returns an error if the input code is not identical to the result of styling. "off", the default, writes back if the input and output of styling are not identical.
