--------------------------------------------------------------
There's another problem with PDTextStream, 8-bit encoded text should be treated
as having PDFDocEncoding, however we see this line:
{quote}
return new String(out.toByteArray(), "ISO-8859-1");
{quote}
Note that ISO-8859-1 is essentially WinAnsiEncoding. PDTextStream is looking
pretty questionable to me, first of all it doesn't actually represent a "text
stream" but "a text string or a text stream", secondly it would be far simpler
to just use COSString given that getAsStream() is never actually called.

> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 1.8.10, 2.0.0
> Reporter: Michele Balistreri
> Attachments: PDTextStream-UTF16.diff
>
>
> the getAsString() method from PDTextStream is quite useful, but it does not
> support UTF-16 text. I added a small check on the first two bytes to support
> UTF-16 content. This is needed because two-bytes encodings do not degrade
> gracefully like UTF-8, even for plain ASCII text and so the resulting string
> is unusable.
