Returns OK or error.


Reads text from file.
You have to decide which encoding to use (if not UTF8). We support a few encodings, but we can add more if you need something special. Some characters will be wrong if the encoding is not correct.
The read text may be shorter than requested if you hit end of file.

When passing UTF-16 as encoding, we can detect byte order if there is a Byte Order Mark.
