I have a bunch of files with a mixtures of encodings mainly ISO-8859-1 and UTF-8.

I would like to make all files UTF-8, but when trying to batch encode this files using
iconv some problems arise. (Files cuts by half, etc.)

I supposse the reason is that iconv requires to know the 'from' encoding, so if the command looks like this

```
iconv -f ISO-8859-1 -t UTF-8 in.php -o out.php

```

but 'in.php' if already UTF-8 encoded, that causes problems (correct me if I'm wrong)

Is there a way, that I can list all the files whose encoding is not UTF-8?
