Guess encoding of files and return configured reader
Description
The purpose of this library is to "guess" the encoding of files, and retrieve
a reader that is properly configured to use the right encoding as guessed.
The library is able to recognize the various Unicode encoding variants:
* UTF-8
* UTF-16LE - Low Endian
* UTF-16BE - Big Endian
* UTF-32
If a Unicode encoding isn't recognized, it's an 8-bit encoding. If the 8-bit
encoding is not US-ASCII, the default platform 8-bit encoding is assumed
whatever it is. However, the library cannot guess between different 8-bit
encodings. Only statistical analysis, n-grams and similar techniques specific
to each language used in those files can help guessing the encoding, but this
is not supported by the library.
