Jukka Zitting commented on TIKA-154:
------------------------------------
Re: Andrzej. The implementation I committed is based on a similar idea than the
one you suggest. It looks at the first few bytes of the document and treats the
document as text if no non-printable control characters are found.
> Better detection of plain text versus binary formats with a text header

> Antoni Mylka noted on the mailing list:
> Many binary formats begin with magic byte sequences composed of ASCII
> characters, e.g.
> zipfiles begin with PK
> pdfs begin with %PDF-
> chms help files begin with ITSF
> etc.
> Tika should do a better job of detecting such cases.
